# Does dragging files to an external drive move them or copy them?

Dragging between **different drives** in Finder **copies** — the originals stay on your Mac, so no space is freed. Hold **Command** while dragging to **move** instead (the pointer changes), or delete the originals after checking the copy.

Dragging within the same drive moves. For big or important folders, copy first, check the copy opens, then delete the original — or use a tool that verifies the move and leaves a link behind, such as Storage Studio.
