.sty File Extension

Developer: N/A
File type: LaTeX Style Document
You're here because you have a file that has a file extension ending in .sty. Files with the file extension .sty can only be launched by certain applications. It's possible that .sty files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .sty file?

The STY format is also known as a LaTeX Style document, and the content of a .sty file contains definitions and descriptions of the specific styling attributes implemented by the creator of a particular LaTeX text document. These LaTeX documents can be saved in the .tex format as well as in the LTX extension. During the creation of a TEX or LTX document, a STY file can be created by the user and associated with the LTX or TEX document. These STY documents are useful for groupware collaboration work, particularly for document presentation development, since the styling descriptions found in the associated STY files will assist others in the improvement of the layout and formatting of the associated LTX or TEX document. There are many text editing software and word processing applications that can be used to open and view these STY files, and one is the TextMaker program. This application has a version for Microsoft Windows users and another version for Mac users. This means users of these two different systems can collaborate and share .sty files without any compatibility issues with the use of TextMaker. Some of the styling descriptions found in an STY file include details of formula structures, line styling definitions and text formatting attributes among other pieces of information useful for users who wish to improve the content of the TEX or LTX documents. Backslashes often precede these descriptions, while users can add their comments about particular descriptions by writing it below the description, and these comments can be differentiated from descriptions or definitions because it is preceded with the percent symbol.

how to open a .sty file?

Launch a .sty file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .sty file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .sty files aren't yet associated with it. In this case, when you try to open a .sty file, you can tell Windows which application is the correct one for that file. From then on, opening a  .sty file will open the correct application.

applications that open a .sty file



ProTeXt was developed by Thomas Feuerstack that works with Windows operating system. This is available in four languages namely: German, Italian, French and English. The file size of the downloadable file is 750 MB. There are third party applications included in this downloadable file in CTAN website and those are MiKTeX, ConTeXt, Ghostscript and TeXnicCenter (now known as TeXstudio). Although, the use of TeXnicCenter is highly discourage by some users. These are some latex editors that can be combined together. In order to utilize ConTeXt in ProTeXt and MiKTeX the users must install a Perl (ActivePerl and Ruby) in the users’ operating system. LaTeX involves TeX and translation of XML and DocBook to PDF files. Thru understanding more about LaTeX, users can productively use ProTeXt. This is a freeware IDE (integrated development Environment) application that focuses in Latex creation and alteration. The latest version of ProText is 3.1 released last July 2012.


MiKTeX is a typesetting structure for Microsoft Windows that is created by Christian Schenk. It consists of an execution of TeX and a set of related programs, and gives the tools needed to prepare documents using the TeX/LaTeX markup language, as well a simple tex editor, named TeXworks. It features easy installation, having a complete set of additions (programs, styles, fonts…) are available to help users typeset their documents, it has an integrated package manager installs missing components from the Internet, if required; having an Update Wizard helps users to keep its system up-to-date by installing the latest package updates, it has a fast previewer, having well maintained package repository and it is an open source, meaning that users are welcome to redistribute MiKTeX under certain conditions. The name derives from Christian Schenk's log-in, “MiK for Micro-Kid”. It can update itself by downloading new versions of earlier installed components and packages, and it has an easy installation process. Furthermore, it gives the users the option whether they wish to download any packages that have not yet been installed but are demanded by the current document. Present version of MiKTeX is 2.9 and is available at the MiKTeX homepage. Since version 2.7, MiKTeX has maintained for XeTeX, MetaPost and pdfTeX and compatibility with Windows 7; and is presently being ported to GNU/Linux, with a beta version being available for testing.

a word of warning

Be careful not to rename the extension on .sty files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .sty. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
