Seek and Destroy Music Duplicates is a tool for locating and removing duplicated music files. It does not crash on corrupted files and normally suggests the best song from amongst the duplicates. It uses an incremental scanning strategy and uses relatively few system resources. MP3, OGG, WMA, and AAC formats are supported.

It allows specified directories to be excluded from the search, and the state of the scanner can be saved to engage incremental scanning when the tool is used periodically. MP3 tag, OGG tag and file data comparators are supported. An XML report can be produced. Duplicates are always moved to the destination folder and not deleted.

Release 1.8 has a scanner strategy control panel. The duplicate-matcher strategy is parameterized. The keep-duplicate-file strategy is parameterized. Strategy parameters can be applied to the duplicates without the need for re-scanning the files. Panel has been added where users can recheck duplicates, uncheck deviant duplicates, or uncheck all duplicates.

Application is a pure Java product and it uses multi-threading capabilities of the Java environment.
