Finding things in Finder · Storage Studio in Finder's sidebar
If I delete a file in the Storage Studio location, is it deleted from my cloud account too?
Short answer: Yes — the folders are your accounts, not copies, so deleting there deletes from the account. Some services keep deleted files in their own trash and some don't; check the provider's website to recover.
Yes. The folders in the Storage Studio location are your accounts themselves, not copies, so deleting a file there deletes it from that account.
Whether you can get it back depends on the service: some keep deleted files in their own trash for a while, others remove them for good. Check the provider's website if you need to recover something.
If you only want to free space on your Mac, don't delete — files in the location stay online-only until you open them, so they take essentially no local space anyway.
