Private Beta

Your drive was clean once.
Let's find out what happened.

Your storage, explained
in terms you recognize.

Categories you actually know

Plugin Data, Sample Libraries, Projects, Bounce Exports, Installers. Not "miscellaneous files." The breakdown matches how you think about your drive.

Drill into what's actually large

Click any folder to see inside it, proportionally. Library → Audio → Plug-Ins → VST3. Every level reconciles to its parent — no double counting, no surprises.

Find duplicates without the risk

Byte-identical files across your drive, found with a three-stage hash cascade. Two tiers: confident duplicates with matching names, and identical-content files flagged separately for review. Nothing is pre-selected.


"I cleaned my drive by hand. Thought I was done. SessionSweep ran and found 30GB more — including a plugin company I stopped using two years ago still sitting at 17GB."

Open and scanning
in under two minutes.
1

Download and install

Open the .dmg, drag SessionSweep to your Applications folder. Done.

2

Allow it to open

Because SessionSweep is in beta and not yet on the Mac App Store, macOS will ask you to confirm. Go to System Settings → Privacy & Security and click Open Anyway. You'll only see this once.

3

Pick a folder and scan

Click Choose Folder & Scan and point it at your projects folder, your home folder, or your whole startup disk. The scan is completely read-only — SessionSweep cannot move, delete, or change any file. It only looks.

4

Tell us what you found

Fill out the short feedback form linked in the app. What surprised you, what confused you, and what you'd trust the tool to do next is exactly what shapes the next version.

This is a read-only beta. The scan, categorization, and duplicate detection are fully working. The ability to move files to Trash is coming in the next release — and your feedback from this version is what decides how it gets built.
