# Why does Eject fast drive say it will quit Xcode, Docker and other apps?

Developer tools such as Xcode, Simulator, Docker, OrbStack and JetBrains IDEs often keep files open on the drive (caches, images, simulators). macOS can't eject a drive while files on it are open, so the eject sequence pauses automatic actions, asks those apps to quit, waits a few seconds, then ejects.

Save your work before clicking **Eject**. If something still holds a file, Storage Studio lists it so you can close it yourself. Click **Resume** in the popover after reconnecting to turn automatic actions back on.

See the [eject guide](https://storagestudio.us/manual/troubleshooting).
