I have a large music collection, and a good number of playlists that I have formed over the years. All the music is neatly organised in a folder hierarchy.
I have managed to get my hands on higher quality versions of multiple albums, and would like to replace the low quality ones with these. But, that would mean that I have to build my playlists again from the scratch, as the new filenames will not be recognise in the old playlists. What is the best option for me to proceed?
One of the ways I thought would work was to see which filename of in new album is closest to the old one, and then rename it with the old filename (i.e. file named 01-Highway-to-Hell.mp3 in new album would be closest to highway_to_hell.mp3 in the old album). How do go about doing this renaming?
