Files that contain the .wal file extension are most commonly associated with the Quake gaming application. The Quake gaming software uses the WAL files to store the game's mapping textures. It then applies the proper textures to walls and other game-related objects within the gaming software.
The .wal file extension is also used to store custom skins that are used by the Winamp media program. Winamp is a multimedia player that allows users to play audio and video media on their computers. The software player was developed by Nullsoft. The skins contained in the WAL files change the look and feel of a user's Winamp interface, allowing users to customize their application environment.
