# When does a locked Delta Drive folder lock itself again?

After a number of minutes without use — **5**, **15** (the default), **30** or **60** — and straight away whenever your Mac sleeps, its screen locks or Storage Studio quits, or when you choose **Lock now**.

When it locks again, the files you opened from it are deleted from your Mac: they were private copies. Changes you made to an opened file are **not** saved back into the locked folder, so to keep a new version, save it somewhere on your Mac and put it in with **Add files…** while the folder is open.

To open it again, double-click it and enter your PIN and the code we email you.
