Unity Editor AssetCache Folder

Bottom Line: It is 100% safe to delete the Unity AssetCache folder. Deleting it will not corrupt your Unity projects or erase your purchased Unity Asset Store licenses.

What is the Unity AssetCache Folder?

Located at %LocalAppData%\Unity\cache on Windows or ~/Library/Unity/cache on macOS, AssetCache is created by the Unity Editor and Unity Hub.

When you download 3D models, textures, audio packs, or code plugins from the Unity Asset Store, Unity saves compressed package copies into AssetCache/packages. Additionally, Unity keeps compiled shader and texture cache artifacts in this directory.

Over time, as you test different Asset Store packages across projects, AssetCache hoards gigabytes of old .unitypackage files you no longer need.

Can You Delete Unity AssetCache?

✅ Yes, it is completely safe to delete.

• No project data lost: Your actual game source code, scenes, and project Assets/ folders live in your project directories and are untouched.
• Asset Store licenses remain: You can always re-download any purchased Asset Store package for free directly inside the Unity Package Manager.
