What is a VRCW file?
A VRCW file is a world created for VRChat, a free-to-play virtual reality (VR) platform in which users create custom avatars and socialize with each other within user-generated worlds. It contains a VRChat world that a user created using the Unity game engine and the VRChat Software Development Kit (SDK). To make VRCW files available within VRChat, users upload the files in the VRChat SDK Build Control Panel.
Released in 2017, VRChat allows users to travel to unique worlds and socialize with each other using VR headsets, microphones, and custom avatars. VRChat users can do almost anything, including host virtual dance parties, run Dungeons and Dragons sessions, or explore simulated mountain passes, within a VRChat world.
VRChat world developers create worlds using the Unity game development engine and VRChat's SDK. They then save their worlds as VRCW files. When a developer has finished creating their world, they can upload it to VRChat as a private world, for use with their friends, or a public world, which will then become available to anyone who uses VRChat. The platform's developers and community test user-submitted worlds in the VRChat Community Labs, before releasing them to the general public. As of 2020, VRChat users had created over 50,000 worlds.
NOTE: Sometimes, VRChat users steal and re-upload other users' worlds, claiming them as their own creations. This practice is generally frowned upon.
How do I open a VRCW file?
