# What does "An app started writing to this while you were deciding, so it was left alone" mean?

Storage Studio checks each item when it lists it **and again** right before it acts. Between those two moments an app started using this one, so acting on it now could disrupt that app. It was left alone.

Once the app has finished — or after you quit it — run the action again.
