The problem

You moved your music to a new drive, renamed a folder, or migrated computers — and now Rekordbox shows hundreds of tracks with the dreaded red icon. Rekordbox's own 'Relocate' workflow only lets you fix one missing file at a time, or a folder at a time if you're lucky.

How Music Library Doctor does it

  1. 1 Install Music Library Doctor and point it at your music folder (or folders).
  2. 2 MLD scans the folder and compares every file against Rekordbox's master.db.
  3. 3 Missing tracks are matched by filename, file size, and audio fingerprint where available.
  4. 4 Review the suggested matches — or accept all automatically if you trust the heuristics.
  5. 5 MLD writes the corrected paths back to master.db. Reopen Rekordbox — the red icons are gone.

Supported today

Rekordbox · Serato DJ · VirtualDJ (incl. Favorite Folders) on Windows 10+ and macOS (Apple Silicon + Intel).

Why native integration matters

Rekordbox's 'Relocate' is deliberately conservative because it writes to the live library. MLD uses the same write path but automates the search across multiple folders and drives simultaneously, and shows you the diff before committing.

Frequently asked questions

What if two files have the same name?

MLD disambiguates by file size, duration, and optionally audio hash. You get a preview before anything is written.

Does it back up my library first?

Yes. MLD creates a timestamped copy of master.db before any write, so you can roll back.

Will this fix tracks across external drives?

Yes — add every drive/folder you want MLD to search. It handles network volumes too.

Does it work if Rekordbox is in cloud-library mode?

MLD repairs the local master.db. If you use Rekordbox Cloud, the changes sync on next launch.
