# How many transfers run at the same time?

Two transfers run at once; any others wait with the **Queued** state and start automatically as soon as a slot frees up, in the order they were added. This keeps your Mac and your connection responsive.

Inside each transfer, several files can move at the same time — that's set by **Parallel transfers** under Advanced options.

If a transfer stays Queued for a long time, check whether two others are running or paused-and-waiting, and whether it needs a drive that isn't connected.
