DT Duplicate finder & Remover For SharePoint
by Data TB Software
Find and remove duplicate files in SharePoint Online. Zero downloads, review first, Recycle Bin.
DT SharePoint Duplicate Finder & Remover scans SharePoint Online sites, document libraries and folders for duplicate files and lets you remove the extra copies from one desktop dashboard. It reads everything through Microsoft's official sign-in without downloading a single file, and every removal goes to the SharePoint Recycle Bin.
SharePoint is built for teamwork, and teamwork creates copies. A contract saved to the project library and again to the client folder, a file shared in a Teams channel, a migration that copied a library twice, a sync conflict that left a "(1)" file behind. SharePoint has no one-click duplicate cleaner, so storage fills up with repeated files. This tool gives you the missing step: a clear list of what is duplicated, where it sits and how much space it wastes.
Two scan modes
- Fast Scan matches files by name and size. It is quick and suited to obvious duplicates and a first look at a large library.
- Deep Scan matches files by content hash, so renamed copies and identical files stored in different libraries are found. Use it before a migration or storage audit.
Key features
- Scan across sites, document libraries and folders in a single run
- Select only the folders you want checked, or the whole account
- Connect multiple accounts and manage them from one dashboard
- Live file count, folder count and per-file status while scanning
- Storage overview showing used, available and total capacity
- Duplicates shown in groups for review before anything is removed
- Bulk removal in one confirmed action, with nothing deleted automatically
- Removed files go to the SharePoint Recycle Bin, not permanent deletion
- Full activity log with timestamps for every scan and removal
- Unlimited data and 500+ file formats including documents, videos and images
Privacy by design
The scan reads only file name, file size and hash value. It never reads document text or image data. Sign-in uses official Microsoft OAuth, so your password is never entered into the app. Nothing is downloaded to your computer or stored on any external server. If your organisation controls third-party app access, a Microsoft 365 administrator may need to approve the app once.
Free scan, paid removal
