I am using a laptop with Vista. I keep all of my music files on my D drive. I see this music in the D drive but when I want to add a file or folder to my Itunes library Itunes does not recongnize the files. This is something that has only recently happened. Maybe over the last 3 or 4 months, that I noticed. Does anyone have any suggestions as to what I am doing wrong or what Itunes may be doing, or not doing, when it looks for these files. They are all Mp3 files.
