What is a VERSION file? A VERSION file is a metadata file used to identify the name and hosted location of a Kerbal Space Program (KSP) mod. It lists a mod's name, location, version, and associated KSP version(s) in a JSON format. Some KSP mod managers, such as KSP-AVC, use VERSION files to retrieve, install, and update associated mods.

The KSP community has created many mods for the game, which allow players to alter the game's gameplay. Some KSP mods are compatible with only certain versions of the game. To help players manage their mods and KSP installations, KSP Add-on Version Checker (KSP-AVC) uses VERSION files to check that a mod is compatible with a player's version of KSP.
