Data Transfers · Data Transfers basics
Can I transfer files directly from one cloud account to another?
Short answer: Yes — choose one connected account as the source and another as the destination in New Transfer. It works across services and between two accounts of the same service. Your Mac runs the transfer, so keep it on and online.
Yes. Pick one connected account as the Source and another as the Destination in New Transfer, choose Copy, Move or a sync, and start. It works between different services (Dropbox to Google Drive, Box to OneDrive) and between two accounts of the same service.
The transfer runs from your Mac, so your Mac needs to stay on, awake and online until it finishes. You don't need room on your Mac for the whole set — files pass through rather than being kept.
Tip: try a Dry run first to see what would be copied, and use Move only when you're sure you want the originals removed after they've been checked at the destination.
