What is it?
Caches of other Google software in ~/Library/Caches/Google, such as Google Drive, Google Earth, GoogleUpdater or Android Studio, depending on what you have installed. Sizes vary from a few MB to several GB.
What happens if you delete it?
Each app rebuilds its cache as needed. No documents or settings are stored here.
How to remove it properly
Quit the Google apps involved, then move the subfolders you want to clear to the Trash in Finder (Go › Go to Folder… and enter ~/Library/Caches/Google).
Quit the app that uses it, then move it to the Trash. Empty the Trash when you’re sure.
Before you delete it
Clearing the cache of the Android Studio version you use makes it re-index your projects at next launch, which can take several minutes.
