ZenPack unpacks, cleans, sorts, and indexes your entire sample library in one run. Point it at the mess. Get back a library you can actually use.
One run. Every archive opened, every junk file gone, every sample where you'd expect it.
"I got into making beats and did what every producer does — downloaded every free pack I could find. Within months I was spending more time digging through ZIPs and folders than actually making music.
I assumed someone had built a tool to fix this. Nobody had. So I did."
— Jay, creator of ZenPack
The same pipeline you see in the app: four numbered steps, a live console, and a single progress bar across the whole run.
Extracts ZIP, RAR, and 7z archives — including packs nested inside packs — into one clean working folder.
Removes broken files, system junk, macOS sidecar clutter, and duplicate-pattern debris before sorting begins.
A deterministic engine routes every sample, MIDI file, and preset into a professional category structure.
Builds a searchable browser of your whole library — with in-browser audio playback — plus a CSV index.
Or skip the steps entirely: press Run Full Pipeline and watch one progress bar take your library from chaos to done.
You search "808" as its own thing — not as a kick variant buried three folders deep. So does ZenPack.
Working at 140? You'll never scroll past 3,000 loops at every other tempo to find the ones that fit.
Drums → Loops → One Shots → MIDI → FX. The folder order mirrors the order you build a track in.
A file the sorter isn't sure about goes to a clearly labeled Unknown folder — never confidently filed into the wrong place.
ZenPack's sorter is a deterministic engine, hand-tuned over months against thousands of real commercial packs. Not a model. Not a guess. Not "it might be different this time."
Every file's destination follows explainable rules — filename plus folder context, with careful word-boundary matching. Run it twice, get the identical result twice.
Hardened against the actual mess producers download: misleading filenames, genre labels that look like content labels, FL Studio bundled samples, beat-promo clips, field recordings.
The engine's core rule: a wrong guess is worse than no guess. Uncertain files go to Unknown, in plain sight — your library stays trustworthy.
ZenPack is built around one promise: nothing happens to your library without you seeing it first.
Your first run shows every move it would make — without touching a single file. You approve the plan, then it runs.
Want your originals untouched forever? ZenPack can build a sorted copy and leave your existing library exactly as it is.
ZenPack organizes with folder structure only. Your filenames — and anything that depends on them — stay exactly as they are.
Source and destination for every single file, recorded. Nothing happens silently. Everything is auditable.
The free demo isn't a video or a sandbox — it runs on your actual files. Unpack your archives, clean the junk, and browse and play your samples in the searchable browser. The license unlocks the sort.
No time limit. No account.
Early-supporter price — increases after launch.
Activation is a simple offline license file: copy your machine code from the app, email it to us, load the .lic file you get back. Done — no restart, no account.
If you're on a normal Windows 10 or 11 PC (64-bit, AMD or Intel) — yes.
Never renames — your filenames stay untouched, always. The Clean step removes only junk (broken files, system files, sidecar clutter), Dry Run shows you everything before it happens, and every action is logged. If you want zero risk, Copy mode builds a sorted copy and leaves your original library alone.
No — deliberately. The sorter is a deterministic engine refined over months against thousands of real sample packs. The same library sorts the same way every single time, every decision is explainable, and files it can't confidently classify are flagged as Unknown instead of being guessed into the wrong folder.
It runs on your real library with no time limit: unpack all your archives, clean the junk, and build a fully working searchable browser where you can search, filter, and play your own samples. The one thing it doesn't do is sort — that's what the license unlocks.
No account, no subscription, no phone-home. The license is a file validated offline on your machine. Buy once, own it.
Yes — a macOS version is planned for a later release. Windows ships first so it can be supported properly. No date promised; it'll release when it's ready.
ZIP, RAR, and 7z — including nested archives (packs zipped inside other packs).
They go to a clearly labeled Unknown subfolder inside the relevant category, where they're easy to find and file yourself. ZenPack's rule is that a wrong guess is worse than no guess — it will never silently bury a file in the wrong place.
