So I did my own research (really, just by trying things out), and tried copying my entire library to another location (one that would have a shorter path) on the same computer, using copy files to organized folder, selecting as my template: <Album>\<Composer>\<Artist>\<Disc-Track#> <Title>). (I used this template because, in general, the album name would have been the name of the original CD, which might have mixed composers and/or artists). That worked very well, but some of the tracks were missing the Album tag, so a folder named Unknown Folder. If I now go through those files and add the correct tags, how to I create the correctly named folder? I guess I could "copy to organized folder" the entire root folder to another root folder using the same template.
On a related topic, I discovered a flash drive containing WAV versions of many of my earlier MP3 files. (Remembering my workflow then, I would rip a CD to a WAV file, then create the MP3 version), If I copy them to the new root folder, using the same template, would that work?
