Kudus and many thanks for this excellent ID3 editor. I run a Mac M1 with several thousand music files obtained variously. A JavaScript music player I found needed the files named sequentially as a number (1.mp3,2.mp3,3.mp3,...). But I had the originals on a different external drive named correctly.
Due to a foolish ID10T error I had bricked the original external drive with all original music files. DUH. Now I wanted to rename my existing .mp3 files correctly. I am able to do some renaming with exiftool and bash if the files contain metadata, however, many do not.
If I create a text file of correct filenames (playlist) I am able to use the proper scripting to import those names into filenames. Wow. What a handy function. This program will save me hours of searching and head banging.
As a programmer I very much appreciate your thought and design abilities in this tool.
