One storage cleaner & optimizer for every byte you keep
TerraBytes is a storage cleaner and optimizer for cloud and on-prem alike. One scan flags every duplicate, outdated, oversized and risky file and shows exactly what they cost you, in euros and in CO₂. Reduce storage costs in one scan, without deleting anything by accident.
What a storage optimizer actually does
A storage optimizer is not just a bigger recycle bin. It is data cleanup software that scans everywhere you keep files, works out which of them are genuinely wasteful, and hands you a plan to reclaim the space safely. The waste has a name: ROT data, redundant, obsolete and trivial files that sit in your storage costing money and carbon without serving anyone.
Most of that ROT is also dark data: information you store, secure and back up but never actually use. It accumulates quietly: the same document copied to three places, drafts nobody deleted, giant exports, media from projects that ended years ago, and files from people who have long since left. Across a whole organization it adds up to a storage bill you are paying for no reason.
TerraBytes finds that waste for you. Instead of guessing what is safe to remove, you get one clear, ranked picture of your entire storage estate, cloud and on-prem, with the biggest wins first.
Every wasteful file, flagged
TerraBytes scans your cloud and on-prem storage and surfaces exactly what you can safely reclaim.
Duplicate files
The same document saved to three sites, "final_v2 (copy)", re-shared attachments: TerraBytes works as a duplicate file finder across cloud and on-prem, matching copies wherever they live and showing how much space collapsing them frees.
Outdated & obsolete data
Files untouched for years, folders from finished projects, and accounts left behind by former employees: classic ROT that is safe to archive or remove once you can see it clearly.
Oversized files & media
Giant videos, raw images, design files and bloated exports quietly eat the largest share of your quota. We flag the heaviest offenders so you fix the biggest wins first.
Risky & non-compliant data
Unencrypted or personal data that creates GDPR and CSRD exposure. TerraBytes flags both the cost and the compliance risk, so cleanup improves your security posture too.
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.
Cloud and on-prem, one scan
Storage waste never lives in just one place, so a storage optimizer that only sees the cloud, or only sees your servers, leaves half the savings on the table. TerraBytes scans your whole estate at once and reconciles duplicates and ROT across the boundary between them.
Connect the storage you already use:
- SharePoint: sites, document libraries and version bloat.
- OneDrive: personal and former-employee accounts.
- NetApp: enterprise file shares and volumes.
- NAS: on-prem network storage that grows unchecked.
- Local drives: workstations and servers on Windows and macOS.
TerraBytes runs on both Windows and macOS, so the same cleanup covers everyone, everywhere your data lives.
How it works
1. Connect. Point TerraBytes at your cloud and on-prem storage. It runs serverless and never moves your files.
2. Scan. One pass across SharePoint, OneDrive, NetApp, NAS and local drives flags duplicates, outdated data, oversized media and compliance risk.
3. Act. You get a prioritized action plan with the storage, euro and CO₂ impact of each item. Define rules to keep, archive or delete. You stay in control, and nothing is ever deleted automatically.
The result: leaner storage, a smaller bill, and a documented, defensible cleanup you can show to security, compliance and finance.

Storage optimizer questions
A storage optimizer is software that scans your storage, finds files that waste space and money, and helps you clean them up. TerraBytes flags duplicate, outdated, oversized and risky files across cloud and on-prem in a single scan, then shows what each one costs you in euros and CO₂ so you can reclaim space by priority.
Point TerraBytes at your cloud and on-prem storage and run one scan. It works as a duplicate file finder across SharePoint, OneDrive, NetApp, NAS and local drives at once, matching copies wherever they live and showing how much space collapsing them frees.
TerraBytes covers both cloud and on-prem storage, including SharePoint, OneDrive, NetApp, NAS and local drives. It runs on Windows and macOS, is serverless and private by design, and your data never leaves your environment.
No. TerraBytes flags and recommends, but never deletes on its own. You decide what to keep, archive or remove using custom rules, so cleanup always stays under your control.
