Opening X files

Did your computer fail to open a X file? We explain what X files are and recommend software that we know can open or convert your X files.

What is a X file?

The .x file extension is most commonly associated with Lex source code files. These files contain source code that has been written in the Lex programming language. The X files can be used to create a C program using a lex utility that is included with most Unix distributions.

The .x file extension is also used for Alysis SuperDisk self-extracting archive files, Microsoft Direct-X SDK files, Stardent AVS X bitmap image files, X-file animation file Direct3D files, FPS Creator Model files, Chemical modeller output files, XBLite program files and X11 server import image files.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
