Rekordbox Collection Tool

Clean, repair and maintain your Rekordbox collection — powered by audio-fingerprinting.

At the core of RCT lies cutting-edge audio-fingerprinting technology that automatically identifies and eliminates duplicate tracks in a Rekordbox library, regardless of tags or audio format — while retaining all essential DJ metadata: cues, loops, beatgrids and playlists. The same technology powers unprecedented automatic track relocation. And RCT goes far beyond duplicate management.

What RCT can do

• Find duplicate tracks by audio fingerprint (and optionally by metadata), then process them without losing playlist entries, cues, loops or other metadata.
• Add newly downloaded tracks automatically: avoid duplicates, replace lower-quality versions while copying metadata across, move files into a target folder by playlist, and convert Serato cues/loops/grids to Rekordbox.
• Reset track locations to make them relocatable again.
• Auto-relocate using a different method than Rekordbox — and relocate Dropbox (CloudSync) tracks too.
• Make Dropbox/CloudSync tracks usable again on macOS Monterey and later.
• Deep-remove tracks, optionally deleting the associated audio file (to a "pre-bin" or directly).
• Merge or copy metadata between identical tracks — keep cues, loops, beatgrids and playlist entries when changing audio type, even between streaming and downloaded files.
• Find orphan tracks that aren't in any playlist.
• Fix grey tracks (set owner) and switch tracks from cloud-stored to local.
• Repair WAV files that won't load on certain CDJ players.
• "Restore Rekordbox 6 Backup" companion app, included.
