What is an ASSETBUNDLES file?

ASSETBUNDLES files mostly belong to Unity. An ASSETBUNDLE file is a container format used by the Unity game engine for storing game assets such as models, textures, audio, and other resources. These files are optimized for efficient loading and memory management within the Unity runtime environment. They can be compressed to reduce file size and download times. The internal file format used by ASSETBUNDLES is typically UnityFS, a proprietary file system developed by Unity Technologies. ASSETBUNDLES allow developers to modularize their game content, enabling dynamic loading and unloading of assets during gameplay. This can improve performance, reduce initial load times, and facilitate updates and downloadable content (DLC).
