Corbett
Corbett Duplicate Cleaner scans a full PC, chosen drives or single folders for duplicate documents, photos, videos and mail files, then sorts the matches by type and selects the extra copies for removal. Filters by name, extension, type and size keep the scan focused. Built for Windows, trial included.

Disk facts
Phones imported twice, downloads saved again as file (1) and file (2), backups copied onto the same drive. Duplicate copies pile up quietly until the disk is full and search returns three versions of every report. Duplicate Cleaner finds those copies across drives and removes them in one pass, the originals left where they were.

Why duplicates keep coming back
Windows has no built-in duplicate finder. Storage Sense clears temp files and the Recycle Bin but never compares one photo with another. Duplicate Cleaner fills that gap by checking every chosen location and grouping identical files side by side.
Core features
Set the scan area, run it, review the groups, filter and remove.
Scan
Location to Scan offers three choices: the full computer, local drives or specific drives and folders. Narrow it to Pictures or Downloads for a quick first run.
Scan results
When the scan ends, matches are sorted under All, Document, Video, Audio and Other. Open one tab and only that kind of copy fills the list.
File details
Duplicate Cleaner lists the facts needed to decide which copy goes. Right click any row and choose Open to see the file itself first.
Scan filters
Filters shape the scan before it starts. Look only for JPG copies, skip a trusted project folder or ignore files under a set size.
Removal
Duplicate Cleaner ticks the extra copies automatically and keeps one of every file. Untick anything to keep, then press Remove and the selected copies are deleted together.
Before removing
Removing files is final, so three habits keep a cleanup safe.
System folders
Skip Windows and Program Files
Programs share identical DLL and config files on purpose. Deleting one breaks the app that needs it, so leave system and program folders out of the scan.
Cloud sync
Pause OneDrive or Dropbox first
A synced folder deletes the same files in the cloud and on every linked PC. Pause syncing, clean up, check the result, then let it sync again.
Backups
Keep one copy outside the PC
Before a large cleanup, copy family photos or work files to an external drive. If the wrong version goes, the backup brings it back.
For space problems inside mail apps, see Gmail storage full after deleting emails and Thunderbird running slow.

File Explorer can sort a folder by name or size, and spotting a few doubles that way costs nothing. Across full drives it stops being practical. The rows below show where.
| Job | File Explorer | Duplicate Cleaner |
|---|---|---|
| Cost | Built into Windows | $29 one time |
| A few doubles in one folder | Sort by name and spot them | Finds them too |
| Copies across drives | Manual search per folder | One scan covers all |
| Group by file kind | Not available | Document, Video, Audio, Other |
| Select extra copies | Click one by one | Ticked automatically |
| Scan filters | Search box only | Name, extension, type, size |
| Blocked files | Silent skip | Listed in Show Error Logs |
| Bulk removal | Manual selection | Remove in one click |
Green rows mark where File Explorer copes alone.
For a handful of doubles in one folder, sorting in File Explorer is enough. To see which folders eat the disk first, try the Disk Space Usage Analyzer .
