Delta Drive, Delta Trust & My Drive · Sharing and comments
What happens if someone I shared with deletes a file?
Short answer: Anything a guest deletes goes to your Delta Drive trash, which they can't reach and only you can empty. Use Put back to restore it.
It goes to your trash, which they can't reach — so nothing a guest removes is actually gone. Only you can empty your trash.
Only people with Read / Write access or higher can bin things inside what you shared. Open Trash and choose Put back to return the item to exactly where it was.
