The Package Manager maintains a cache for packages that you get from the Asset Store. The Package Manager stores this cache in a default location, which you can override.
You might want to override the Asset Store cache location for several reasons:
By default, the Package Manager uses the following folder structure for its Asset Store package cache:
<asset-store-cache-root> └── Asset Store-5.x └── <subfolders for Asset Store vendors>
For information on the default location of the Asset Store package cache root, see Location of downloaded asset files.
Note: The Package Manager maintains separate caches for registry packages and Asset Store packages. For information on overriding the default location for the global cache, see Customize the global cache location.
To override the default location of the Package Manager’s cache for Asset Store packages, you can use the following methods:
ASSETSTORE_CACHE_PATHenvironment variable method isn’t permanent, but advanced users might find it preferable in specific use cases.
To use the Preferences window to override the default location of the Asset Store package cache, follow these steps.
Use one of the following methods to open the Preferences window:
Select the Package Manager category.
Under My Assets open the menu beside Cache Location .
Choose Change Location.
Choose a new location for the Asset Store package cache.
In scenarios that involve automation or continuous integration, it’s less practical and more error prone to configure settings in a configuration file or a preferences window. In such scenarios, you might consider setting the
ASSETSTORE_CACHE_PATH environment variable to override the default location of the Asset Store package cache.
Important: Follow these guidelines when you use this method:
ASSETSTORE_CACHE_PATHenvironment variable every time you launch Unity.
For information on setting environment variables, refer to the documentation for your operating system. For an introduction to environment variables, see https://en.wikipedia.org/wiki/Environment_variable.
