The WAL image format is associated with Quake II, a popular first-person shooter video game launched in the late 1990s. WAL files store texture data and might be part of other similar games by Quake II's developer, id Software. The WAL extension is considered rare and it's probably impossible to open outside the game programs it was created for.
The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. This software is extremely efficient in managing a wide range of batch conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert multiple WAL files as once.
