itunes backup issues

[kkamin]

I didn't realize that some of my band names or album names have duplicates due to character casing. example: "Radiohed" and "radiohead". So itunes creates two folders, one for each version. It's not a problem until I tried to backup my itunes folder to an external drive. I get an error message that states it cannot continue copying because it can't copy two folders with the same name but different casing.

My question is, is there some easy way to have itunes or OSX sweep through the itunes folder and try to locate these duplicates? I've been going through manually, but I was hoping there is a better way.

Thanks!
