Remove downloaded Unity Asset Store assets from your drive without leaving Unity Editor
Note: not tested on Mac OS X.
Note: may not work well with large collection of assets.
Via Package Manager: https://github.com/marked-one/AssetRemover.git
Using version: https://github.com/marked-one/AssetRemover.git#1.0.0
Or you can simply copy the AssetRemoverWindow.cs file into your project.
Open the Asset Remover window via Tools/Asset Remover.
You should probably also open the Package Manager window alongside the Asset Remover, like in the screenshot above. In Package Manager window, switch to My Asssets and use Filters to set Status->Downloaded.
If needed, change the Asset Store Cache path to the real path to the Asset Store cache folder and then press the Update Asset List from path button.
Use the Remove buttons to remove assets. Asset is immediately removed from the drive.
