How can we help?
Detect Duplicate Candidates Standard, Ultra
Find the same audio file living in different folders in your library — matched by filename and exact audio length.
What it is
Finds the same audio file living in different folders — matched by filename + exact audio length. Distinct from Remove Duplicate Records, which handles dupes that were imported into the database multiple times that are in the same folder.
Where to find it
Database menu → Detect Duplicate Candidates. Requires the Delete Records permission. Standard and Ultra editions only.
Running a scan
- If records are selected, choose Entire Database or Selected Records. Either way the whole DB is scanned; “Selected Records” just filters results to groups containing a selected record.
- Cloud, encrypted, and HTTP records are excluded.
Results dialog
Two tabs: Duplicate Candidates (N) and Ignored List (N).
Duplicate Candidates tab
- Default keeper — Keep Newest (default) or Keep Oldest pre-checks every copy except the keeper in each group.
- Click a sound row to audition it from the start. SPACE pauses/resumes. Right-click reveals the folder in Explorer/Finder.
- Click a group’s filename header to skip it for this session only.
- Ignore button on a group’s header sends it to the Ignored List — it won’t appear in future scans until you un-ignore it.

Deleting
- Delete Records — drops the records from the database; files on disk stay. Confirmation includes a “stop these files from re-importing” checkbox (on by default) that adds each deleted file to its folder’s
_blacklist.xmlso a rescan won’t bring them back. - Delete Records + Files — also permanently deletes the audio files. Requires the Delete Files permission. No undo.
Ignored List tab

- Lists every group you’ve ignored on this database — filename, length, copy count, ignored-on date, and folder paths.
- Un-ignore on a row brings just that group back on the next scan.
- Reset Ignore List at the bottom clears everything (confirmation required).
- If a brand-new copy of an ignored file shows up in a new folder, the group resurfaces for review.
- The Ignored List is personal and per-database (tied to your OS user account + the active database). It doesn’t sync to shared/remote libraries.
