Under folder 1 there are 12 folders, under each one about 50 files. Let's say folder one is "Bach concertos", I'd like to change automatically all the files' album field to "Bach concertos" (their parent folder name) and I'd like the same action to be done throughout all the twelve folders, bach sonatas, bach suites etc, without doing it one by one.
This task is probably quite basic, I'd like to do the same thing with the artist field. Let's say under baroque folder, change all the folders under vivaldi, and bach, and geminiani etc.
How to do it?
