256 File - opening and understanding

Did your computer fail to open a 256 file? We explain what they are used for and recommend software that we know can open or otherwise handle your .256 files.

What is a 256 file?

Files that contain the .256 file extension are usually associated with the Descent 2 software gaming application. The 256 files contain the RGB color palette that is used to describe the colors that are used by the game's PIG texture files.

Each 256 file that is referenced by the Descent 2 software is associated with a related PIG file. For example, the texture1.pig file would have an associated texture1.256 file associated with it.

The PIG files that the 256 files are associated with are stored in the main directory of the gaming software. The 256 files, on the other hand, are saved in the DESCENT2.HOG file. User's can create custom PIG files by saving the files to the Descent 2 directory and storing the associated 256 file in the user's HOG file.
