The duplicate file finder for cloud and on-prem
TerraBytes is a duplicate file finder that scans SharePoint, OneDrive, NetApp, NAS and local drives in one pass, finds every exact and near-duplicate copy across your systems, and shows what those copies cost you, in euros and in CO₂. Find duplicate files everywhere they hide, then remove them on your terms.
Why duplicate files pile up
Nobody sets out to store the same file five times, yet every organization does. The same document gets re-uploaded to a new site instead of linked. Someone downloads a file, edits it, and saves a fresh copy next to the original. Email attachments get dropped into shared drives by three different people. Backups and exports leave whole trees of duplicated content behind. And cross-site sharing quietly clones files from one team's space into another's.
Individually, none of this feels like a problem. Multiplied across a whole storage estate, it becomes a large, invisible tax: storage you pay to keep, secure, back up and power, for files that add nothing. A dedicated duplicate file finder is the only practical way to see the full picture, because duplicates rarely share a name and almost never sit in the same folder.
TerraBytes finds those copies for you across every system at once, ranks the biggest wins, and hands you a clear plan instead of a guessing game.
Every kind of duplicate, flagged
TerraBytes surfaces duplicates you would never find by browsing folders, across every system at once.
Exact duplicates, by content
TerraBytes matches identical files even when their names differ: "report.pdf", "report (1).pdf" and "report_final.pdf" collapse into one group with the space they waste made visible.
Near-duplicates & versions
Renamed copies, lightly edited variants and repeated saves of the same document. These near-duplicates waste just as much space as exact copies but are almost impossible to catch by eye.
Duplicates across systems
The same file living in SharePoint, on a NAS and in someone's OneDrive. TerraBytes matches duplicates across cloud and on-prem in a single scan: the copies single-system cleaners never see.
The cost of keeping them
Every duplicate group is priced in storage, euros and CO₂, so you can see the real cost of the clutter and fix the most expensive duplication first.
Most of it is waste you can reclaim

See your whole storage estate in minutes, not weeks of manual auditing.
Cost and carbon shown on every result, so you fix the biggest wins first.
Private by design: your data never leaves your environment.
Nothing is deleted automatically; you set the keep, archive and delete rules.
How it works
1. Connect. Point TerraBytes at your storage: SharePoint, OneDrive, NetApp, NAS or local drives. It runs serverless and never moves your files.
2. Scan. One pass looks across your whole estate at once and groups the files that are true duplicates, even when their names, folders or systems differ. Copies that live between systems, which single-system cleaners never connect, are caught too.
3. Review the impact. Each duplicate group shows the storage, euro and CO₂ you would reclaim by collapsing it, so you fix the biggest wins first.
4. You choose what happens. Nothing is deleted automatically. For each group you decide whether to keep, merge or delete, using rules you set. TerraBytes flags and recommends; you stay in control of every action.

Duplicate file finder questions
TerraBytes runs a single serverless scan across your storage and groups true duplicates. Copies of the same file are flagged even if they have different names, live in different folders, or sit in different systems, so you can collapse them and reclaim the wasted space.
Yes. One scan spans SharePoint, OneDrive, NetApp, NAS and local drives, and matches duplicates across all of them. That means it catches copies of the same file that live in different systems, which single-system cleaners miss entirely.
Yes. Beyond exact duplicates, TerraBytes surfaces near-duplicates: renamed copies, slightly edited versions and repeated saves of the same document. These variants waste just as much space as exact copies but are far harder to spot by hand.
No. TerraBytes flags and recommends; it never deletes anything automatically. You set the rules and decide whether to keep, merge or delete each group of duplicates, so cleanup stays fully under your control.
