Files that contain the .xp3 file extension are commonly used for TVP XPK3 virtual file systems.
The XP3 files that are used by these file systems are archive files that have been created using the TVP 2 game construction system. This file format is a very common format for Japanese video games.
An XP3 file is similar to a container file and will normally consist of an archive of the game files that are used to create the associated video game software.
KiriKiri, a scripting engine created by W. Dee, also uses the .xp3 file suffix. These XP3 files contain the resource archives that are stored by the KiriKiri software.
