Point it at a folder. It lists every file with its type, size, dates and SHA-256, then opens each one far enough to say what it is carrying: who wrote it, whether text was deleted under tracked changes, whether comments are still attached, whether a photograph has GPS coordinates in it, whether a spreadsheet has hidden sheets, whether anything calls out to a server when it opens. What normally takes two days with a spreadsheet and a lot of double-clicking. Nothing is uploaded.
Nothing chosen yet. Every file is read here in this tab.
Office documents. Author, who saved it last, the company name, how long it was edited for, the internal title, how many tracked-change marks it holds (including deleted text still sitting in the file), how many comments are attached, hidden worksheets, and any address the document calls out to when it opens.
Photographs. GPS coordinates, camera make and model, the body serial number that ties a photograph to a specific camera, the software that touched it, and when it was taken.
PDFs. Author, the software that produced it, and the page count. It does not read the page content, so text hidden under a black rectangle will not be flagged here. X-RAY is the tool that finds those.
Everything else is listed with its type, size, dates and digest. A digest identifies a file byte for byte, which is what lets somebody confirm later that the set they received is the set that was scheduled. PROOF does that check.
It does not decide what is disclosable. It says what each file contains beyond its visible content and which ones warrant a look. That judgement is yours, and if you are under a disclosure duty it is the duty that governs, not this page. Nothing here is legal advice.
It does not change anything. Files are read and never written. If a schedule flags a document you intend to send out, SCRUB is what removes what it found.
Nothing is uploaded. Every file is opened in this browser tab. Closing the page leaves nothing behind except the schedule you chose to download.
