# Why won't Storage Studio move my Mac's temporary area to the external drive?

Your Mac's temporary area is scratch space every app uses, often before the external drive is even connected. If it lived on a removable drive, apps would fail whenever the drive was away. So Storage Studio offers to **clear** what's safe to clear there instead of moving it.
