.TEX File Extension
File Type 1LaTeX Source Document
Document prepared by LaTeX, a high-quality typesetting system; can include text, symbols, mathematical expressions, and graphics; commonly used in computer science, electrical engineering, and physics for typesetting articles, books, and other publications.
LaTeX files also use the .LTX extension.
File Type 2Texture File
|Category||Raster Image Files|
This file is saved in a binary format, which requires a specific program to read its contents.
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.
