No subscription. No cloud. Your files stay on your machine.
01
Deep Library Scan
Scans every drive and folder you point it at. Finds music files other tools miss — MP3, FLAC, WAV, AAC, AIFF, and more.
02
Smart File Organization
Reads metadata tags and sorts by Artist → Album → Track. Creates clean folder structures automatically from your existing tags.
03
Duplicate Detection
Finds exact duplicates and near-duplicates. Shows you what it found before moving anything — you stay in control.
04
One-Click Undo
Changed your mind? Every organize operation is reversible. Stacker logs every move and puts everything back exactly where it was.
05
Windows & Mac
One license covers both platforms. Download on your Windows machine and your Mac. No extra charge, no questions asked.
06
Your Files Stay Yours
Everything runs locally. No internet required after download. No cloud. No subscription. No account needed to use the app.
How It Works
Three Steps. Clean Library.
01
Point Stacker at your music
Select your music folder, a specific drive, or let Stacker scan everything. Works with any folder structure — even the messy ones you've been ignoring for years.
02
Review what it found
Stacker shows you every file it found, every duplicate, and exactly where it plans to move things. Nothing moves until you say so.
03
Hit Organize. Done.
One click sorts your entire library into a clean Artist → Album → Track structure. Takes seconds. If you don't like it, hit Undo — everything goes back.
