Data Transfers · Problems and messages
Why did some transfers disappear after I removed a cloud account?
Short answer: Removing an account also removes every transfer (one-off or scheduled) that uses it, after showing them to you. Only the records go — files already transferred stay where they are.
Transfers that use an account can't run without it, so when you remove the account, Storage Studio removes the transfers — one-off and scheduled — whose source or destination is in that account, stopping any that are running. You're shown the related transfers before you confirm.
Only the transfer records are removed. Files already copied stay where they are, both in the cloud and on your Mac.
If you connect the account again, set those transfers up again with New Transfer.
