How to open RTF? How to open a .RTF file? What's in RTF files

This format was defined by Microsoft as the standard format for exchanging text documents. Therefore, this format is similar in purpose to the SYLK format for spreadsheets. RTF is supported by many Microsoft products. For example, since version 2.0, it has been introduced into Windows as a Clipboard format, which makes it possible to exchange data between various Windows applications. In addition, the RT format is supported by WORD for Macintosh from version 3.X and WORD for PC from version 4.X.

RTF only uses character-representable codes from the ASCII, MAC, and PC character sets for document exchange. In addition to text, the file in RT format contains control commands in a readable form.

The document consists mainly of control commands for setting up a reader for files in RTF format. These commands can be divided into control words (control words) and control characters (control symbols).

The control word is a sequence of characters with a delimiter (delimiter) at the end:

\lettersequence

The control word is preceded by a backslash "\" (backslash). The following characters can be used as delimiters:

Space (space), moreover, this symbol refers to the control word;
Number or "-" sign. These characters must be followed by a delimited parameter. A space or other characters, except for numbers and letters, can be used as a separator;
All characters other than numbers and letters. These symbols do not apply to control word.

The RT format uses the letters "A" through "Z" and "a" through "z" and the numbers "0" through "9" to specify the escape sequence. National characters do not apply to control information.

As, control characters separate letters are used. Each control character is preceded by a backslash "\":

\control symbol

Only a few of these symbols are currently defined. Therefore, unknown characters may be skipped when reading.

In the RT format, it is possible to combine individual sequences into groups using brackets:

(group start) group end

Such groups are created, for example, when describing footnotes, headers and footers, etc. If you want to place the characters "\", "(" or ")" inside plain text, then they must be preceded by a backslash:

\\ \{ \}.

This allows a program reading an RTF sequence to recognize that the character should not be interpreted as a control character.

The RT format also uses some character codes to control printing.

CR and LF characters within text will be skipped. Microsoft uses these characters for greater clarity when presenting an RTF file. Inside the control words, the characters CR and LF can have a special meaning, more about this will be discussed in the description of the commands.

Special control words

RTF has special-purpose control words. Let us briefly consider these words and their purpose.

Control word change page number displays the current page number.

Control word change footnote activates the automatic numbering of footnotes.

By using change date you can display the current date.

By using change time you can display the current time.

\chftnsep

Indicates a change in the line separating footnotes from text.

This sequence is used to enter the text of the formula.

Indicates a sub-item of an index.

Text may be skipped when reading RTF format.

Specifies a hard (non-breaking) space between two words, i.e. in this position, the sentence cannot be split when wrapping to the next line.

Symbol stands for soft hyphenation (nonrequired hyphen).

Symbol stands for unbreakable hyphen (non-breaking hyphen) where the word cannot be divided.

The sequence allows direct input of hexadecimal numbers in the text. They are given instead of the characters hh.

This sequence sets the transition to a new page.

This sequence causes a line break in the text.

With the help of this sequence, the end of a paragraph is marked in the text. Subsequence \par can be replaced by the sequence \ 10 or \ 13. Wherein \10 matches ASCII character code 10 (carriage return). ASCII code 10 (CR) cannot be entered directly because it is ignored by the reader.

This sequence marks the end of a text fragment or text paragraph.

This sequence replaces the tab stop. You can also directly set the ASCII code 09H.

End of table (column).

End of table (row).

Destination control words

The control words described below can be used to perform basic configuration of the RTF reader. They can only occur at the beginning of a document or at the beginning of a group. All operators along with parameters must be enclosed in parentheses, for example:

(\rtf0\pc.......)

The format of some operators is described below.

\rtf<параметр>

Specifies the start of the file. As a parameter, the program that creates the file can specify the version number. For example:

(\rtf0.......)

The label must be at the beginning of the file. This statement may be followed by other statements or a closing parenthesis.

Setting the type of encoding for the saved text is carried out using the following operators:

\ansi: text is stored in standard ASCII format. This format is used, for example, in Windows.
\mac:. text is stored in Macintosh encoding
\rs: the text output uses the IBM-PC character encoding.
\rsa: IBM-PC Code Page 850 (model PS\2).

To transfer texts between different systems, the \ansi encoding must be used.

\colortbl

Windows and other programs use palettes to determine which colors to use. Most often, the palette consists of 16 different colors, obtained by combining the primary colors - red, green and blue. Team \colortbl allows you to change individual definitions in the palette. For each color, the table indicates the value of the red, green and blue components. Each color is described by three parameters:

\red000 \green000 \blue000

Instead of 000, the value of the color fraction is specified in the range from 0 to 255. Example: in a table consisting of 16 colors, colors 0 and 2 must be redefined. To override colors, the following sequence can be given:

( \colortbl \red128\green64\blue128\;;\red0\green64\blue128; )

The color definition ends with a semicolon. Since the 1st color remains unchanged, there are two ";" characters in the sequence follow one after the other. The sequence ends with a closing bracket.

Operator \cfn defines the background color (with the default setting n=0), and the operator \cbn- symbol color (with standard setting n=0).

\fontbl

This operator is used to build a font table and correlates the name of a font (font group) with number font. When defining a font, you can use the following operators:

\fnil: the name of the font group is unknown. The output should use a standard font.
\froman: Roman fonts must be used (e.g. Times Roman)
\fswiss: this operator specifies the use of fonts from the Swiss group (Helvetica, Swiss, etc.)
\fmodern: Pica, Elite and Courier fonts can be used.
\fscript: italic fonts of the Script group are used.
\fdecor: when specifying this operator, fonts must be selected from the Decor group (Old English, etc.).
\ftech: selection of a group of fonts with technical and mathematical symbols (SYMBOL, etc.).

The command to create a font group can consist of the following statements:

(\fonttbl\f0\fnil default;) (\fl\froman roman h;) (\f2\fswiss helvetica;)

After keyword \fontbl followed by the first font number \f0. Next comes the definition of the font group. Here, after the number 0 is indicated \fnil, those. group name unknown. The next parameter specifies the name of the font to select (for example, roman h). indication default tells the reader to use the standard font. The font name is followed by a semicolon. In the example above, only fonts numbered 1 and 2 are defined. The entire sequence can be grouped with curly braces.

The font table must be filled with values before the operator is encountered \stylesheet or text. The standard font is entered by the operator \defn.

\stylesheet

This operator defines the font of the paragraph, i.e. the size, style, and name of the typeface, as well as how the text of the paragraph is aligned. It uses two key parameters:

\basedon000: instead of the characters 000, the number of the font type that is used as the current one is indicated.
\snext000: assigns the number of the next type of font (style), which - will become current.

An operator might look like this, for example:

(\stylesheet\s0\f3\fs20\qj Normal;) (\sl\f3\fs30\b\qc Heading Level 3;)

Fonts are numbered from 0 to n ( \s0...). In the first line paragraph style 0 ( \s0) is assigned the name Normal. Text output is done in font 3 ( \f3), 10 points in size ( \fs20). Parameter \qj says that the inscription should be format aligned. The second line defines font style 1, which gets the name Heading Level 3. The font has a size of 15 points, bold ( \b = bold) and the inscription is centered on output ( \qc).

\pict

This operator is used when describing a drawing in bitmap format. The following parameters contain the description of the picture as hexadecimal values. Parameters can be selectively used to define the geometry of a drawing or its format:

\pich000: operator specifies the height of the drawing in pixels. Instead of three zeros, a numeric value is substituted. If there is no operator, the drawing height is determined from the current drawing data. With the help of the parameter, you can set a certain height for the picture.
\piw000: operator sets the width of the picture in pixels. Everything said about the previous operator is true.
\picscaled: with this operator, the picture is scaled so that it exactly fills the area allotted for it.
\wmetafile: the parameter specifies that the data is stored in the Windows metafile format. The n parameter specifies the metafile type (1 = MM-text).
\macpict: parameter specifies that the data is stored in Macintosh Quick-Draw format.
\bin000:. parameter specifies the number of bytes. Instead of three zeros, a hexadecimal number is written.
\wbitmapn: the parameter specifies the format of the bitmap. The n parameter specifies the type (0 corresponds to a logical bitmap).
\brdrs: defines a simple frame for the picture
\brdrdb: defines a double border for the picture.
\brdrth: defines a bold line for the picture frame.
\brdrsh: defines a shaded frame for the picture
\brdrdot: defines a dotted line for the drawing.
\brdrhair: defines a thin line for the picture frame.
\picwGoaln: sets the desired image width in twips
\pichGoaln: sets the desired height of the picture in twips.
\picscalexn: sets horizontal scaling (n can take values from 1 to 100, default is -10).
\picscaleyn: specifies vertical scaling (n can take values from 1 to 100, default is 10).
\piccroptn: describes the top margin of a picture in twips. If the parameter n is positive, the upper part of the picture is cut off. Negative values of n make it possible to draw a frame around the picture. The default value of n is 0.
\piccrorbn: describes the bottom margin of a figure in twips. For positive values of the n parameter, the lower part of the picture is cut off. Negative values of n make it possible to draw a frame around the picture. The default value of n is 0.
\pissrporrn: describes the right margin of a picture in twips. With positive values of the n parameter, the picture is cut off on the right. Negative values of n make it possible to draw a frame around the picture. The default value of n is 0.
\piccropln: describes the left margin of a figure in twips. If the parameter n is positive, the picture is cut off on the left. Negative values of n make it possible to build a frame around the picture. The standard value of n is 0.
\wbmbitspixeln: defines the number of bits per pixel for a bitmap (default value is 1).
\wbmplanesn: specifies the number of bitplanes (default is 1).
\wbmwidtbbytesn: specifies the length of the bitmap in bytes

I don't even know what to say to that...

200?"200px":""+(this.scrollHeight+5)+"px");">This project was created by a novice Delphi programmer so I'm waiting for your comments.

Well, if you want - here's my opinion for you, but just don't be offended.
I will say that the project was executed badly. Why? Firstly, it looks ugly, and in our age of super-technologies, a beautiful shell is indispensable - no matter how many functions there are. Why is it ugly? Okay, the standard shell of a Windows application is fine for a beginner. But you can't scatter components like that! It looks crooked and creates the feeling that everything is sketched in a couple of minutes, anyhow. Specifically: the buttons on the panel are small, and there are no captions to them, no tooltips. The pictures are not very clear. The picture above the "open" button is wrong. The purpose of some is unclear, for example: an incomprehensible button (far right on the left panel), incomprehensible input fields with up and down arrows. The settings menu looks terrible and only opens on the "txt format" tab. And what are those tabs? It was impossible to make a simple window? Better yet, as an MDI application, they are still quite popular. I almost forgot - the program icon does not match the program ...
Second, it's inconvenient to use. As I said: tabs, settings menu (which could be done in the main pop-up menu). The "file" menu item is not yet clear. Where are the items "new", "save as"? And the item "actions" should be called "edit", because this is more understandable to the user. In the same paragraph there is no "cut" button - it is not convenient to copy and then delete. "Settings">> "Open settings" is terrifying. I already said - it was better to do all the settings in the "settings" item, in the drop-down list. But some (if there are a lot of settings), issue a separate form or frame (frame - such as the properties of the form and the panel at once, which is convenient). There is no help at all, at least about who the creator is, and even better describe how to use it. Each time you start the program appears somewhere at the bottom of the screen. It is better to do auto-centering at startup - it is not known which monitor the user has. And even better - saving the position of the form in the ini file... Well, that's it, for the future... And one more thing: it's better to hide the toolbars, depending on what format is currently being edited. And the inscription with arrows indicating on the panel - throw it out, only interferes. And yet, I advise you to use hiding or deactivating components, the use of which is not possible at the moment. And, of course, a window with the question "save documents before exiting?" never be superfluous, even if there is an autosave ...
That, in general, is all that I could notice. Good luck with your programming, you still have a lot to learn...

P.S. Here's another one I almost forgot:

200?"200px":""+(this.scrollHeight+5)+"px");">Source Code: Yes;
...
License type: Do what you want;

Hehe, but there is no source code. I don't think you know where Delphi source code is stored. Or did you mix something up... In short, you forgot to pack Unit2.pas and Unit3.pas files. That's where all your source code is. Here, sir...
And finally: the program is small, but you used an installer, and some dubious one at that (Avast! suggested running in a sandbox). Use simple WinRAR archiving, or, if you want, make the auto-unpacker the same WinRAR (or other archiver). And to compress the program into exe, I advise you to use ASPack, usually a 400kb program is compressed to 100, but the code is unpacked into RAM before launch - this method is not very suitable for large programs.

The RTF file format is familiar to many document users. A lot of business documentation, e-books and brochures, texts of various kinds and content - they all exist, including in the form of rtf files. When it becomes necessary to view the contents of such documents, the well-known text editor MS Word comes to the rescue, easily opening files of this type. But is this the only alternative? Of course not. In this article I will tell you how to open an RTF file, what programs will help us with this, and how to use them.

As is known, " .rtf' is a form of text file extension. This letter combination is an abbreviation for the words " Rich Text Format” (enriched text format). A document in this format supports the so-called “rich text” (rich text), which allows you to edit the document with several text formatting options, different fonts and their sizes, place JPG and PNG images inside the text, support custom tab settings, and so on.

The format was created by Microsoft in 1987, has gone through several modifications over the course of 20 years, and in 2008 Microsoft announced the termination of its support. However, "rtf" is now one of the most popular text formats.

Usually, the RTF text format is opened on almost any user's computer (usually using the installed MS Word text editor). If you do not have access to view files of this type, then I recommend installing and using one of the programs that I will list below.

The best programs to open rtf files

There are a sufficient number of programs that allow you to open text files with the rtf extension. The algorithm for opening such files is standard: you launch the appropriate program, click on the “File” tab in it, select “Open” there, and indicate to the program the path to the desired rtf file on your PC disk.

Among the software products of RTF viewers, I can recommend the following options:

Microsoft WordPad is a simplified text editor from Microsoft, usually included with Windows since Windows 95. Allows you to view, edit and save text files in the rtf format;

Microsoft Word - the popular text editor I have already mentioned, is part of the Microsoft Office suite of applications. The current version of the product is Microsoft Office Word 2016;
Microsoft Works is a simplified office suite for home use. The text editor of this package in terms of its functionality is something between the already mentioned WordPad and MS Word, providing effective support for the rtf format;
Atlantis Word Processor is a shareware text editor for Windows OS. Among its advantages are compactness (it takes only 3 megabytes) and speed of processing rtf files;
TextMaker Viewer is a free application for Windows OS that can open and view the vast majority of text documents, including the rtf format we need;
Corel WordPerfect Office X6 is a well-known office software package from Corel, which includes the WordPerfect X3 text editor, there is support for the rtf format. The product has a paid character;
Apache OpenOffice is a free office suite that is a great alternative to paid Microsoft Office. The text editor (Writer) included in this package effectively supports working with rtf files;
AbiSource AbiWord - a free text editor, similar in functionality to MS Word, can be an effective answer to the question "rtf with what to open";
TextMaker is a text editor included in the SoftMaker Office suite. Also has support for rtf format.

A file of this format is supported by other text editors that can work with formatted text.

How to open rtf file online

There are also several online tools that allow you to view and edit rtf online. I would note the Google Docs service, which allows you to view rtf documents online.

You can also install the appropriate extension (Docs Online Viewer) for Google Chrome or an equivalent for Mozilla Firefox, which allows you to open rtf files using the functionality of these browsers.

In addition, you can use online converters (for example, Zamzar), which allow you to convert your rtf document into a text format that is more convenient for you (for example, into the equally popular "doc").

Conclusion

The programs listed above will help you with the issue of editing RTF extensions. I recommend paying attention to free alternatives, in particular, to the OpenOffice office suite, which will allow you to work with files of this type absolutely free. For conservatives, I can recommend the template Microsoft Wordpad and Microsoft Word - many users, whatever one may say, choose them.

In contact with

Extensions are some of the files associated or which can be opened with the Microsoft WordPad. RTF files are text documents that can be created, opened, viewed, edited or changed using word processing applications for both Mac and Microsoft Windows-based computers, like Microsoft WordPad for Windows and Microsoft Word 2011 for Mac. It gives the users a wide cross compatibility support, which was the central objective for the improvement of the Rich Text Format technology, and these .rtf files can even be opened, viewed and used with database applications. The OpenBSD Unix platform is frequently utilized in computers running as Web servers of a secure network. OpenBSD files may be saved in directories of the OpenBSD system that were generated upon installation of the software applications. Files with the .openbsd extension can be opened by standard text editors, particularly well-known like Microsoft Notepad, and this text editor may also be utilized to create and edit OPENBSD files. Files with the .readme extension are text documents engaged to give users with beneficial information and specific details about certain applications installed in the system. These files can be opened, viewed and edited with a selection of text editors including Microsoft Notepad and Microsoft WordPad.

Microsoft Word

Microsoft Word is a word processor program that is packed in the Microsoft Office Suite . It is developed by Microsoft Corporation, generating a .doc file extension when the file is saved. A document file format (.doc) is a text or binary file format for saving documents on a storage media, mainly for computer use, like typing text, charts, tables, page formatting, graphs, images and other documents whose content is created and edited. Contents of these documents are printable in any sizes and are capable to open in other devices provided that its operating system is able to read DOC files. This .doc file extension has become extensive de facto standard for office documents, but it is an owned format and is not always totally supported by other word processors. A variety of programs that is able to open this type of file, and different operating systems and have installed programs that can open a 1ST file are: Microsoft Word, Microsoft Notepad, Microsoft Word, IBM Lotus WordPro, and Corel WordPerfect.

Microsoft Notepad

Notepad is a basic text editor used to create plain documents. It is commonly used to view or edit text (.txt) files, and a simple tool for creating Web pages, and supports only the basic formatting in HTML documents. It also has a simple built-in logging function. Each time a file that initializes with .log is opened, the program inserts a text timestamp on the last line of the file. It accepts text from the Windows clipboard. This is helpful in stripping embedded font type and style codes from formatted text, such as when copying text from a Web page and pasting into an email message or other Ã¢â‚¬Å“What You See Is What You GetÃ¢â‚¬ Â text editor. The formatted text is temporarily pasted into Notepad, and then immediately copied again in stripped format to be pasted into the other program. Simple text editors like Notepad may be utilized to change text with markup, such as HTML. Early versions of Notepad offered only the most basic functions, such as finding text. Newer versions of Windows include an updated version of Notepad with a search and replace function (Ctrl + H), as well as Ctrl + F for search and similar keyboard shortcuts. It makes use of a built-in window class named edit. In older versions such as Windows 95, Windows 98, Windows Me and Windows 3.1, there is a 64k limit on the size of the file being edited, an operating system limit of the EDIT class.

Microsoft Works

Microsoft Works is an incorporated package software that was developed by Microsoft. It is less expensive, smaller, and has fewer features than Microsoft Office or other office suites. Its central functionality includes a word processor, a spreadsheet and a database management system. Newer versions have a calendar application and a dictionary while older versions included a terminal emulator. Files with WPS extension is utilized for output files of the Microsoft Works word processing application. These files are classified as text documents that can be created, saved, viewed and edited using the Microsoft Works program. Microsoft Word 2010, Microsoft Publisher 2010, Planamesa NeoOffice, and OxygenOffice Professional are some of the applications that are able to open and view the content of these WPS files. The contents of these WPS files can also be exported to other compatible word document formats. this promotes convenience and efficient document presentation, group collaboration and sharing between users of different systems and word processing applications; however, WPS document cannot be applied with macros and other formatting options available in Microsoft Word; so Microsoft discontinued support and development of the Microsoft Works application with its version 9 and the release of Microsoft Word 2010.

notepad2

The Notepad2 application is a more advanced text editor for Windows developed by Florian Balmer. This program originated from the original built-in Microsoft Notepad which is why it is also effective and fast even when it is small. Notepad2 also has a lot of features such as syntax highlighting that allows a text or a source code to be displayed using different fonts and colors. This syntax highlighting feature of notepad2 allows users to write programming language easily and distinctly. This amazing function of Notepad2 is also owing to several other features it possess such as auto indentation, regular and expression-based find and replace feature, bracket matching, newline conversion, encoding conversion as well as multiple undo and redo features. These features make the function of the simple Notepad more advanced and it makes Notepad more interesting to use either to open files in .txt format or to write HTML codes. Notepad2 also supports many programming languages such as ASP, C++, Perl, Java, etc.

Today we will take a closer look at RTF (format). This abbreviation stands for Rich Text Format. This is a popular text file format. They support a wide range of formatting options.

RTF files: what is the format

Text in this format can be bold, italic, or underlined, and the user can select colors and fonts for printed characters. RTF (format) allows you to set different widths of line spacing and set indents along the edges of the sheet. This solution is incredibly popular among users.

Solution from Microsoft

First of all, RTF (format) can be opened thanks to the Word application, which is part of the MS Office package. This is one of the most successful products of this corporation, which is currently the standard in the field of office document processing. The solution has an attractive interface presenting all its functions. The Microsoft Office suite, in addition to the Word application we need, also includes the following components: Visio, Designer, SharePoint, Project, OneNote, InfoPath, Access, PowerPoint, Outlook, Excel. The component we need can be installed separately and in a group with others. Note that Word is the world's leading text editor.

Kingsoft Writer

If you need to open books in RTF format, this application will help you. This is a free text editor, which is similar to the above Word program. The tool is part of the Kingsoft Office solution. However, you can install it separately. The program has a classic interface, typical for text editors. Thanks to the application, you can create and format text documents, as well as supplement them with formulas, graphs, charts, three-dimensional symbols and images. There is another reason for the Word analogy. A separate window has been implemented here that allows you to insert various characters that are not available on the keyboard. All materials can be instantly converted to PDF without additional tools. The implementation of the tabbed interface allows you to run multiple files in a single window.

Alternative Solutions

There are other programs through which you can interact with the RTF format. One of them is OpenOffice.org. This is a full-featured office suite with multilingual support. This solution runs on all major operating systems. OpenOffice.org makes it possible to store all data in its own open ODF format. It is approved by the international organization for standardization ISO. The developers have also provided a built-in function for exporting materials to PDF format with one click. In addition, the solution supports Flash technology. A user-friendly interface is easy to learn and use, in particular for owners of the Microsoft Office package. Note that the use of the application does not require a license fee. Anyone can install it on a computer.

The next application that supports RTF is called Notepad2. This is a fast and small text editor with syntax highlighting. The application has a simple and attractive interface. As you type, lines are counted. Notepad2 can run without installation and does not use the system registry. There is also a convenient text search feature with extended functionality. In addition, the tool can be minimized to tray. Implemented here and the function of transparency.

AbiWord can also help us in solving the problem. It is a tool for processing text documents. It allows you to print, edit and create various materials, as well as work with letters and messages.

In addition to the programs described, RTF (format) can be opened using the LibreOffice application.
