# Why does it say the in-use check ran out of time on a large folder?

Storage Studio checks whether any app is writing to a folder before moving it. On a very large folder that check can run out of time. That means it **doesn't know** whether something is writing to it — not that nothing is.

Quit anything that uses the folder, then click **Check again**, or continue if you're certain nothing is using it.
