It counts everything first.
Every file, every folder, true recursive sizes. The numbers start moving before the first second is up, and the 800 GB folder stops hiding behind three subfolders.
Vaultline Labs / Drive Inspector 0.3.2
Reads the drive. Never writes to it.
Point it at a drive.Get the space back.
Drive Inspector finds every file your drive is storing twice — matched on contents, never on filename, and confirmed with a full SHA‑256 hash. Click any one of them to reveal it in Finder and clear it out. On the way it tells you your codecs, your biggest folders, and where the space actually went.
- Reveal any duplicate in Finder. One click from the result to the actual file, so clearing a drive takes minutes instead of an afternoon.
- Matched on contents, not names. Verified with a full SHA‑256 hash, so a duplicate is a fact rather than a guess.
- Any drive, RAID or mounted share. About a minute for a shoot drive. Nothing uploaded, nothing written back.

01 The room nobody wants to open
Forty-one drives. One label that helps.
Every one of them was carefully backed up by someone who is no longer on the project. None of them can tell you what is inside without being plugged in, opened, and guessed at.
Plug one in. Give it sixty seconds. Find out.
Then it reads the headers.
Codec, resolution, frame rate, duration, camera make and model, capture date — pulled straight from the container. It never decodes a frame, which is why it stays fast on a full volume.
Then it proves the duplicates.
Group by exact byte size. Partial-hash the survivors. Full SHA‑256 anything still standing. Filenames are ignored entirely — two files match because their contents match, or they do not match at all.
And hands you a number.
Only verified extra copies of files over 4 MB count toward it, so it is a floor rather than an optimistic estimate. Take it to the person who signs off on storage.

03 The part that saves the afternoon
Finding them is the easy half.
A list of duplicate paths is not much use if you then have to hunt each one down by hand. Every result here is a button: click it and the file is revealed in Finder, selected, ready to drag to the trash.
Both sides of every pair, the hundred largest files, the folders that quietly took over — all of it one click from the real thing. Drive Inspector never deletes anything itself. It just stops the search being the slow part.

04 What you walk away with
A document, not a dashboard.
Most disk tools draw you a sunburst chart and leave you to interpret it. This one produces a file you can send to someone — self-contained, logos inlined, opens offline in five years on a machine that has never heard of Vaultline.
HTML to forward. PDF to staple to the storage request. CSV when you want to do your own arithmetic on all of it.

05 The part you should not take on faith
It cannot phone home.
Not a privacy policy. Not a pinky promise in a footer. The app ships without the network entitlement, which means macOS itself will not let it open a socket — there is no code path, and no permission to take.
Run this on the DMG before you ever launch it. If you find a network entitlement in that output, do not install it.
$ codesign -d --entitlements :- \
/Applications/Drive\ Inspector.app
<!-- sandbox on -->
com.apple.security.app-sandbox true

06 The catch
There isn't one.
Vaultline builds custom media operations systems — searchable archives, AI tagging, transcripts, drive tracking — for production teams with real footage libraries. Drive Inspector is one finished piece of that indexing engine, cut loose as its own tool instead of living inside a sales conversation.
It is not a trial and not a crippled demo. It does one thing, completely: tell you the truth about a drive. If that is useful on two drives, that is the whole product and you owe us nothing.
If it turns out to be revelatory across two hundred, you will know where to find us — and that is the entire business model.
07 Before you install a stranger's binary
Reasonable questions.
Can it delete my files?
No. There is no delete capability in the app at all. It reports what it found and can reveal any file in Finder; every decision after that happens in Finder, by you.
Does anything get uploaded?
No. The app is sandboxed with no network entitlement, so it is structurally incapable of sending anything anywhere. Run
codesign -d --entitlements on the download and read it yourself before you install.How can you be sure a duplicate is really a duplicate?
Files are grouped by exact byte size, survivors are partial-hashed, and anything still matching is confirmed with a complete SHA‑256 hash of the whole file. Names are never used. Reclaimable bytes count only verified extra copies of files 4 MB and larger, so the headline number is a floor.
How long does a scan take?
A typical shoot drive lands somewhere between a few seconds and a couple of minutes, because it reads headers rather than decoding frames. Very large volumes take longer, and a mounted network share scans at the speed of the connection. Results populate live, and a scan can be stopped and resumed.
Will it run on my Mac?
Natively on Apple Silicon and Intel, macOS 13 Ventura and later. The download is a signed and notarized DMG, so it opens normally — no right-click-Open workaround, no security warning.
What happens to my email address?
It goes to Vaultline. We use it to send you the download and, now and then, a note when the tool gets better — nothing else. We do not sell it or share it, and one reply gets you removed for good.

Worst case, your drives are in better shape than you feared — which is also worth knowing before the next storage invoice lands.
