Sortsi turns messy folders into organized ones by looking at what's actually inside your files, not just their names or file types. Point it at Downloads, Desktop, Documents or any folder you choose. Sortsi reads each file on your PC, works out what it is, and proposes a clean set of folders and clear file names. You see the whole plan before a single file moves. A PDF invoice from Comcast becomes "2026-03 Comcast Invoice.pdf" in Finance › Invoices. A boarding pass screenshot lands in Travel. Résumés, tax forms, receipts, contracts, class syllabi, installers, archives, photos and videos each go where they belong. SEE EVERYTHING FIRST Every proposed move and rename is listed, and you can switch each one on or off. Change any name or destination, review the files Sortsi isn't sure about, or save the plan to finish later. A "Why this folder?" note explains each decision, and a before-and-after view shows your folder as it is now next to how it will look. ALWAYS UNDOABLE Every change is recorded. Undo a whole cleanup or a single file from History, even days later. Sortsi never permanently deletes anything: extra copies go to the Recycle Bin, and Undo brings them back. FIND DUPLICATES Sortsi finds exact copies of the same file, even when they have different names, and spots near-identical photos like bursts, edits and resized copies. You choose which copy to keep. PRIVATE BY DESIGN Everything runs on your PC and works with Wi-Fi off. Your files, file names and contents are never uploaded anywhere. CAREFUL WITH YOUR SYSTEM Sortsi leaves Windows and program folders, app data, shortcuts, code projects and cloud-only OneDrive files alone. Files that are open in another app are skipped and reported. One purchase includes everything. There's no subscription and nothing extra to buy.
