External drives · Upgrading, transferring and backing up the drive

How do I move everything to a new, bigger external drive?

Short answer: Use More → Drive → Transfer Drive…. It copies everything to the new drive, verifies it, then re-points every moved app and folder at the new drive. Your old drive is left untouched as a fallback.

Use Transfer Drive… in the popover's More → Drive section. It copies everything on your current drive to the new one, verifies the copy, then switches over — re-pointing every moved app and folder at the new drive and making it the active one.

  1. Plug in both drives and open Transfer Drive….
  2. Pick the new drive; Storage Studio checks it and runs a quick speed test.
  3. Start the copy and watch progress (or close the window — it keeps going).
  4. When the copy is verified, Storage Studio inspects it and switches over, asking once for your administrator password if any shortcuts are in protected places.

Your old drive is never modified or deleted — it stays as a complete fallback.
