Delta Drive, Delta Trust & My Drive · Linked folders and copies
What happens when I unlink a folder from Delta Drive?
Short answer: Unlinking forgets the connection and deletes nothing on either side. If the Mac folder disappears (say, an unplugged disk), the link stays and says so, and the drive copy is untouched.
Unlink from this Mac forgets the connection; nothing is deleted on either side. Stop keeping this folder… on the Copies screen likewise deletes nothing.
If the folder on your Mac goes away — an unplugged disk, a folder you moved — the link is kept and says so (the Copies screen shows the folder on this Mac isn't there any more), rather than quietly disappearing. What's already in your drive is untouched.
