Database Clean-up
The Database Clean-up tool removes old data such as playout log items, voice tracks and uploaded audio store files, freeing up disk space. Orphaned files are files in the voice track recordings folder or audio store folder that are no longer referenced by any track or voice track item in the PlayIt Manager database.
Database Clean-up is found under the Tools section.
