Atrium Zip & Unzip
SharePoint cannot open a zip file. This can. Select an archive in any document library and choose Extract: see what is inside, tick what you want, and put it in the folder you pick. Select files or folders and choose Zip to make an archive with the name you want, saved back to the library.
£795 + VAT, one Microsoft 365 tenant, one payment. Unlimited users, libraries and archives.
What it does
- Extract into the current folder, a folder you choose, or a new folder named after the archive, keeping the folder structure
- Preview before extracting: see every file, untick what you do not want, and see which are risky or blocked
- Safe extract: path tricks and zip bombs are stopped, and your admin sets which file types are blocked or allowed
- Zip your way: choose the name, save it in the library or download it, keep folders, and add an AES-256 password
- Large archives: files are streamed and uploaded in chunks, with a progress bar and a result report
- Conflicts handled: skip, overwrite or keep both, and one bad file never stops the rest
- Undo extract: remove everything an extraction created in one click, with the recycle bin as a safety net
- Extract and tag: set column values on every extracted file
- Auto-unzip rules per library, with an activity log
- Send as zip: an expiring link for people in your organisation
- Fixes garbled file names in archives made on computers using other languages
- Reads and writes .zip, .tar and .tar.gz

Why not the built-in download as zip?
SharePoint can zip selected files, but only as a download, with a name it chooses, and it cannot save the result back or open a zip you already have. The Power Automate extract action stops at 50 MB and 100 files. Atrium Zip & Unzip works in the library itself, on archives of any size your browser can handle, and tells you exactly what it did.
How does auto-unzip work?
When someone opens a library that has a rule, new archives that match its file name pattern are extracted as that person, and the result appears in the activity log. It runs while the library is open, so it suits inboxes and drop folders that people use, rather than overnight processing.
