What is a VRCA file?

VRCA files mostly belong to Unity. VRCA files are used in VRChat to store detailed avatar data. They are built as Unity asset bundles using the internal UnityFS format.
When you access a VRCA file with VRChat or a Unity tool, you see the full set of avatar components. These files hold:

3D model data (mesh and textures)

Animation and rigging information

Configuration settings for physics and interactions

FilExt.com note: This file format lets users import and update their custom avatars. For more technical details, visit Unity.
