Use cases

# Where exact duplicates quietly pile up.

Anywhere files get copied, backed up or shared more than once, exact duplicates accumulate. Here's where DuplicateDuster earns its keep — and which folder goes on which side.

Creative & media archives

## Years of project exports, several times over.

The challenge.Video and design projects get exported, re-exported and copied to a second drive 'just in case' — and those exact copies never get cleaned up. Nobody dares delete anything, because nobody is certain which drive holds the real one.

With DuplicateDuster.Put the canonical project archive on the source side and the working drives on the target side. Every match is paired across the two, the archive copy is never selectable, and whole re-copied project folders come back as a single finding instead of four thousand file rows.

- The archive is structurally protected — no checkbox, no accidents
- Folder-level matches for whole projects that were copied wholesale
- The size pre-pass means a terabyte of unique footage is never read

Backup sprawl

## When 'better safe than sorry' becomes three full copies.

The challenge.Manual backups taken at different times duplicate the same files repeatedly, especially when whole folders get re-copied instead of just the changes. Three generations of backup, one live share, and no idea what the overlap is.

With DuplicateDuster.Point the source at the live share and the target at the old backup generations. The reclaimable total tells you exactly what the overlap costs before you touch anything — and the free tier gives you that number without a licence.

- Read-only scan; nothing changes until you confirm
- Full reclaimable-space report is free and uncapped
- Empty backup folders left behind by a cleanup are pruned automatically

Photo libraries

## The same photo, imported from three devices.

The challenge.Importing from a phone, a camera and a sync folder leaves the exact same photo sitting in several places under different names — and renaming means a filename comparison finds none of it.

With DuplicateDuster.Matching is by content, so the same shot is recognised wherever it landed and whatever it's called. Keep the library, clear the import folders, and see the gigabytes come back.

- Filename never matters — only content
- Filter to image extensions to keep the result set focused
- Recycle bin by default, so a wrong call is recoverable

Shared drives & departments

## A shared folder where everyone saved their own copy.

The challenge.Shared drives accumulate duplicates fast when several people each save a copy of the same document or asset instead of linking to one. Deleting someone else's copy is a political act as much as a technical one.

With DuplicateDuster.Every copy is listed with its full path, so you know exactly whose folder each one lives in before anything is removed — and hard-link mode reclaims the space while leaving every path working, which nobody has to be consulted about.

- Full paths shown for every copy in a group
- Hard-linking frees the blocks without breaking anyone's links
- Recursive scanning covers the whole share in one pass

Migrations & consolidation

## Two file servers becoming one.

The challenge.A merger, a NAS replacement or a cloud migration means copying one tree into another — and quietly paying to store, back up and migrate every file that already existed on the other side.

With DuplicateDuster.Compare the incoming tree against the destination before the move. What's already there comes back as folder-level matches, so you migrate the delta instead of the whole thing.

- Cross-drive and cross-volume matching by content
- Folder matches show the overlap at the level you'd actually plan around
- Cancel mid-scan without losing the machine to a runaway job

Regulated & sensitive data

## Redundant copies you're not supposed to be keeping.

The challenge.Data-minimisation obligations don't just mean deleting old records — they mean not holding six copies of the ones you do keep, scattered across working folders nobody inventoried.

With DuplicateDuster.Find every redundant copy against a designated system of record, remove them with a three-pass overwrite where a normal delete isn't enough, and do all of it on a machine with no network connection.

- Runs entirely offline — safe for material that can't leave the room
- Optional secure erase with the SSD caveat stated up front, not buried
- System locations refused outright, whatever ends up selected

## See exactly how a scan runs.

From nominating the two sides to a reviewed list of matches and the space they're costing you.
