I use iTunes for my music player on my computer (I don't own an ipod.) However, I had a lot of wma files so I let iTunes convert those to .mp3. However, now I have a ton of songs where I have both the wma version and the mp3 version. I would like to delete all the wma files I have and have them replaced by the newly created mp3 files (which were put into a separate itunes folder by itunes.) is there a way to do this easily with a program so i don't have to do it manually folder by folder?
