# Do I need an external drive to remove duplicates?

No. Finding and removing duplicates works without one. What a drive changes is where removed copies wait:

- **No drive set up** — removed copies go to your Mac's Trash, which still uses space until you empty it.
- **Drive set up and connected** — they rest in the Recycle Vault on the drive, recoverable for about 6 months, and the space leaves your Mac straight away.
- **Drive set up but unplugged** — they're held safely on your Mac and moved to the drive when you reconnect it.

That's why the full safety net works best with an external drive.
