Finding things in Finder · Storage Studio in Finder's sidebar
What is the "Storage Studio" entry in Finder's sidebar?
Short answer: It's Storage Studio's Cloud Drive: a Finder Location where each connected cloud account, your external drive's Home folder and Bridge-shared device folders appear as folders. Files download when opened, and edits sync back.
It's Storage Studio's Cloud Drive: one place in Finder's Locations sidebar, next to iCloud Drive, Google Drive and Dropbox, where each cloud account you've connected appears as a folder — plus your external drive's Home working folder and any folders shared from devices connected with Bridge.
Files show as online-only until you open them, then download on demand, just like other cloud drives. You can open, edit, rename, move and delete files there, and changes sync to the account.
It's on by default and appears as soon as there's something to put in it. There's nothing extra to install, and it goes away when you quit Storage Studio.
