Consolidate your scattered music folders

MLD's Folder Consolidation Wizard moves every track into a single target folder and rewrites every playlist reference — Rekordbox, Serato, VirtualDJ — in one coordinated step.

The problem

Most DJ libraries drift over the years. You rip some CDs to Music/, download from Beatport into Downloads/Beatport/, drag iTunes exports into iTunes/Music/, and end up with a library spread across 17 folders on two drives. Neither Rekordbox nor Serato nor VirtualDJ has a 'consolidate library' button, and doing it manually means either breaking every playlist or carefully relocating files one by one.

How Music Library Doctor does it

  1. 1 Install Music Library Doctor. It reads your Rekordbox, Serato, and VirtualDJ libraries and computes where every referenced track physically lives.
  2. 2 If your library is spread across too many folders, MLD shows a **scatter banner** on the dashboard with a one-click launch for the Folder Consolidation Wizard.
  3. 3 Pick a target folder (local drive, external SSD, or NAS). MLD shows a dry-run preview: which tracks will move, how many bytes, and whether the target has enough free space.
  4. 4 Confirm. MLD moves the files, then rewrites every Rekordbox master.db, Serato crate, and VirtualDJ database.xml reference to the new location — in one coordinated pass.
  5. 5 Reopen your DJ apps — every playlist points to the consolidated folder. Zero broken links.

73 seconds: the plan before anything moves — how many tracks, how much space, whether any collide, and what would cross to another drive.

Why native integration matters

Doing this by hand means either moving files first (and breaking playlists) or relocating playlists first (and having nothing at the new location). MLD coordinates the move with simultaneous updates to every DJ app's database, so there's never a moment when the library is half-broken. The scatter banner surfaces the problem automatically, so you don't have to go looking for it.

Frequently asked questions

What counts as 'scatter'?

MLD looks at how many distinct root folders your library touches. Libraries spread across many small folders trigger the scatter banner.

Can I target an external drive or NAS?

Yes. MLD handles local disks, external USB/SSD, and network volumes. The wizard verifies free space before starting.

What if the move is interrupted?

MLD is transactional per file — a file either fully moved and was relinked, or it wasn't. Re-running the wizard picks up where it left off.

Does it handle external drives that unplug later?

Yes. Tracks on unplugged drives are treated as offline, not deleted. They stay in your library and get relinked when the drive returns.

Is the original folder structure preserved?

You choose. The wizard can flatten everything into one folder, mirror the existing subfolder structure, or organize by artist/album.
