.TEX File Extension

A TEX file is a source document prepared by LaTeX, a high-quality typesetting system. It may include text, symbols, mathematical expressions, and graphics. Academic and professional users in computer science, electrical engineering, statistics, economics, and physics often utilize TEX files when typesetting articles, books, and other publications.

You can open TEX files with various LaTeX applications, such as TeXworks (multiplatform), MiKTeX (multiplatform), and Texmaker (multiplatform).

Since TEX files store documents in plain text, you can also open and edit the files with a text editor, such as Microsoft Notepad (bundled with Windows) or Apple TextEdit (bundled with macOS). However, these text editors do not provide helpful LaTeX syntax highlighting features available with LaTeX applications.

Several applications, including TeXworks, LyX/Mac, and LaTeX Editor, can convert TEX files to other formats.

For example, select File → Save As... in TeXworks to convert TEX files to one of the following formats:

• .LTX - LaTeX Document
• .BIB - BibTeX Bibliography Database
• .STY - LaTeX Style
• .CLS - LaTeX Document Class File
• .BLG - BibTeX Log File
• .BBL - BibTeX Generated Bibliography File
• .TXT - Plain Text
• .PDF - Portable Document Format

Bitmap image used for storing textures; can create the appearance of different surfaces and can be applied to both 2D and 3D objects; often used in video games (such as first person shooters) that support 3D texture-mapping.

Example video games that use TEX files include Avalon Heroes (which actually uses the .DDS format for its TEX files), Serious Sam, and Dead Rising 2. To open the TEX files used by Dead Rising 2, first rename them to have the ".big" extension, and then open them with Gibbed's DeadRising2 Tools.

TEX files can be opened by some programs that reference textures or use texture-mapping. They may possibly be opened with a generic image editor.
