De-Dup Indexes every time it launches

[alunwebb]

Running perfect tunes 2025-06-16 - every time I launch De-Dup it goes through the indexing process, which is currently taking in excess of an hour to go through 30000+ tracks each time. Can't see any reason why it not saving the cache, music is on an external drive, but even it I just close the program and relaunch it straightaway it starts the indexing process again. Am I missing something?

Yes, it indexes and saves the results, something must be off. Which system, Windows or macOS?

[alunwebb]

Windows 11 Pro

[Spoon]

Open Windows File explorer and type:

%appdata%\PerfectTUNES

into the address bar, there should be a whole bunch of files there, and if your library is a good size the size of a file called 'InfPropsNTags' will be 50MB or more.

Look at the file sizes in that folder.

[alunwebb]

Have attached screenshot of files in that location, the file size for that file appears to be 156Mb

If the date on the audio tracks change, they will be reindexed.
So run Album art, let it index, when it shows, close the program and open immediately, it should not reindex.

[alunwebb]

ran album art for first time and that indexed quickly, found 90 odd files missing art, closed it an re-ran it, didn't index again, just more or less went to show the 90 tracks missing artwork

Ran De-dup and it has started the index process again, having already indexed everything yesterday last time it was run.
