Rebuilding Playlists after Filename converting

I used the Filename convert feature to standardize the syntax of my source filenames so they contain artist - song name - album name), and now I am trying to figure out how to correctly rebuild my m3u playlists so they match the changes, but they are all corrupted now. I used the load playlist option, and then tried to run the same file conversion feature settings on the playlist file references, to match the new entries for the source files but it didn't work.

Is this possible as my playlist are unique and I can't build them from scratch.

Also, is there any benefit to having the track number in the source filename is is this just a matter of preference(I have the track number in the tag still). I noticed my MP3 player is now not showing the songs in proper track order on my player and wondering if this is the cause.

Thanks for any help you can provide.

If regenerating the playlists is not an option for you, you can try Playlist Repair (site in german).

Kind regards,
