Where does Google Drive cache metadata on my device?
base directory:

/data/data/com.google.android.apps.docs/


files explicitly stored on device:        

.../files/fileinternal/&lt;filehash&gt;/&lt;file&gt;


cached files and thumbnails:

.../cache/diskCache/


metadata:

.../databases/


the drive-supported files (like docs, spreads, presos) are in com.google.android.apps.docs.editors.&lt;foo&gt; datadir
