How to Clean Your Rekordbox Library Without Losing Cue Points

The Fear Is Real

Every Rekordbox user who's considered cleaning up their library has had the same thought: "What if I lose my cue points?"

You've spent hours setting hot cues, adjusting beat grids, and organizing playlists. The idea of a cleanup tool accidentally wiping that work is terrifying. And it should be — some tools do exactly that.

Here's how to clean your library safely, without risking any of your Rekordbox data.

Understanding Where Rekordbox Stores Data

Before cleaning anything, you need to understand what lives where:

Your audio files (MP3, FLAC, WAV, AIFF):

These are just files on your hard drive or USB
They contain the actual music
ID3 tags live inside these files (title, artist, album, etc.)

Rekordbox's database (separate from your audio files):

Cue points, hot cues, memory cues
Beat grids and BPM analysis
Playlists and folder structure
Waveform data
Play history and ratings

The key insight: CrateGuard does not need to edit the Rekordbox database to analyze audio files. Scanning can remain read-only, but moving or deleting an audio file can still break the file path Rekordbox expects. Treat analysis and file actions as separate decisions.

Step 1: Scan — Don't Modify

The first rule of DJ library cleanup: use a read-only scanner. Any tool that modifies your audio files during scanning is a risk.

What "read-only" means:

The tool reads your audio files to analyze them
It never writes to, renames, or modifies any file
It never touches Rekordbox's database files
It creates a report, not changes

CrateGuard scanning is read-only by design. It reads your audio files, generates fingerprints, and builds a duplicate and quality report without writing to the scanned files.

Step 2: Review Before You Act

After scanning, you'll see duplicate groups ranked by quality. Don't rush to delete. Review each group:

Check which copy is in your Rekordbox collection. That's the one with your cue points.
Check quality. If the copy without cue points is higher quality (e.g., FLAC vs 128kbps MP3), consider replacing rather than just deleting.
Check playlists. If a track is in an active playlist, don't remove it without updating the playlist first.

Step 3: Remove Duplicates Safely

When you're ready to remove duplicates:

Move, don't delete. Move duplicates to a "Duplicates" folder on your desktop. Don't permanently delete yet.
Check Rekordbox. Open Rekordbox and see if any tracks show as "missing" (red exclamation mark). If a track you moved was in your collection, you'll know immediately.
Wait a week. DJ with your cleaned library for at least a week before permanently deleting the moved files.

If you moved a referenced track, return it to the original path or use Rekordbox's supported relocation workflow. Confirm the reference inside Rekordbox rather than assuming it has reconnected.

Step 4: Handle USB Exports

If you export to USB for CDJs, your exported USB has its own copy of the audio files plus a PIONEER database folder. Cleaning your main library doesn't affect already-exported USBs.

After cleaning your main library:

Re-export affected playlists to USB
Your cue points travel with the export (they're in the Rekordbox database)
The USB will now contain only the tracks you kept

What NOT to Do

Don't rename audio files that are in Rekordbox. Rekordbox tracks files by path. Renaming breaks the link.
Don't use "clean metadata" tools that rewrite ID3 tags. While this doesn't affect cue points, it can cause Rekordbox to lose track of files.
Don't reorganize folders without relocating in Rekordbox first. Use Rekordbox's built-in file management if you need to move things.
Don't touch the PIONEER folder on exported USBs. That's Rekordbox's database.

The Safe Cleanup Workflow

1. Scan with a read-only tool (CrateGuard)
2. Review duplicate groups and quality scores
3. Identify which copies have Rekordbox cue points
4. Move (not delete) the lower-quality duplicates
5. Check Rekordbox for missing files
6. DJ for a week with the cleaned library
7. Permanently delete moved files if everything's fine
8. Re-export to USB

Quick Wins

Even without removing anything, a library scan tells you:

How many duplicates you have — many DJs are shocked at the number
Which files are low quality — 128kbps copies hiding among 320s
Which files are corrupted — better to find out now than mid-set
Which duplicate files are candidates for archiving — the recoverable space depends entirely on your own library

Knowledge is power. Scan first, act later.
