I have a bunch of MP3s and all of them were on my windows partition. I was in mandrake 9.1 and I right clicked on my desktop, found add new drive. I found a tab where I could select the drive and then hit ok. Now I can double click on the drive and access all my files in windows.
Edit:
Sorry about that. I was using KDE 3.1 and once I had opened the new drive windows I went to the third tab from the left and there are a list of drives to select. I selected /dev/hda1 because I was dual booting. I then clicked ok and a harddrive icon appeared on my desktop. I doubleclicked on it and there was all the folders on my windows partition. I went into windows, desktop, and finally to my MP3 folder on my windows desktop.
