What is an XP3 file?

XP3 files mostly belong to Kirikiri by kikyou. An XP3 file is a data package containing audio clips, text, images, and patches created with Kirikiri scripting engine. Kirikiri was originally used as a visual novel engine for Kirikiri Adventure Game System. Type-Moon visual novels and games like Fate/stay night and Fate/hollow ataraxia are based on Kirikiri engine, so they use XP3 data packages. Nekopara visual novel is based on a modified version of Kirikiri engine which also uses XP3 packages.
