When you download a
.unitypackage file, the Unity Package Manager stores it in the Asset StoreA growing library of free and commercial assets created by Unity and members of the community. Offers a wide variety of assets, from textures, models and animations to whole project examples, tutorials and Editor extensions. More info
See in Glossary cache. Each time you import a downloaded package or a custom package, the Unity Package Manager stores it in the
Assets directory in your project.
You might want to delete a package from the Asset Store cache to free up space on your local hard drive.
Important: Deleting a package from the Asset Store cache doesn’t remove the same package from any projects where you use that package. If you also want to remove the same package from a project, see Remove imported assets from a project.
To delete a package from the Asset Store cache:
Open the Package Manager window.
Open the Packages menu and select the My Assets context.
Select the package you want to delete.
The publisher’s name, located below the package name in the details section of the Package Manager window.
