After scanning your computer, without any way of filtering the amount of disks/volumes (1st BIG problem), you get track list sorted by track name. This track list has Title, Album, Artist, File location columns. 2nd BIG problem : No creation date, no last update date, no file size, no music quality informations The track list cannot be sorted by any other column (3rd BIG problem) Explanations : During years I made several copies of my music library and continued to add music in the latest « version » Now that I reinstalled a new machine with a 3Tb HDD, I discover that I have up to 4 versions of the same track, sometimes with updated tags, sometimes not. Having a list of 90000 tracks without any way to sort out by folders to select 10000 tracks in one shot, it will take me days to sort out this mess Appart of consolidate the whole bunch of music in one folder, I may be able to look at duplicates. Silly ! why should I duplicate 250Gb of music somewhere ? The « search for duplicate » displays more details in more columns but it is also impossible to sort out by other columns that the track name. Conclusion, in my particular case, this tool isn’t 20€ worth.
