External drives · When the drive is unplugged

\n

My Mac is nearly full and the fast drive is unplugged — what can I do?

\n

Short answer: Reconnecting the drive helps most, since moving files there can't run while it's away. Meanwhile Storage Studio can still clear caches and temp files, reclaim old snapshots and make cloud files online-only.

\n

Plugging the drive back in is the biggest single thing you can do, because moving things to it is the largest safe option — and moves can't run while it's away. Until then, Storage Studio can still free space on your Mac alone:

\n
  • Clear caches and temporary files with Free Up Space.
  • Reclaim old local snapshots.
  • Make downloaded cloud files online-only.
  • Look at What's Using Space for large downloads you no longer need.
\n

If a clean-up was waiting for the drive, it says so ("Waiting for your fast drive to come back — this picks up on its own") and finishes when you reconnect. See Freeing space.
