However if the oldest file is currently used in the Viewer (for example for playback of recorded video), it would not be deleted and the next oldest file will be deleted instead. Deletion will continue until the free space rises above this threshold again. See Chapter 7 for saving files.

When the free disk space increases above this level by deleting old video files, the Storage Server resume recording video and generates an event.
