Can I connect a Box account to Storage Studio?
Short answer: Box isn't an account type you can add right now. With Box's own Box Drive app, your Box files appear as a folder in Finder, which you can use in Storage Studio — for example as a Local folder account.
Box isn't one of the account types you can add in Storage Studio right now. If you use Box Drive, Box's own Mac app, your Box files appear as a folder in Finder, and you can work with that folder in Storage Studio.
Add that folder as a Local folder account to give it a nickname for transfers, or pick it as an ordinary folder. Box Drive streams files on demand, so reading them may download them first. See Local folder accounts.
