Duplicate songs on Fuze

i was using auto detect.  as far as what black-retangle advised…i am not computer savy and WMP is the easiest for me. i’m so frustrated this thing was setup just fine until i just added a cpl more songs…now there are dupes all over this device. most of my songs were purchased thru Walmart…then i placed on a cd then ripped the cd onto WMP. i’m not sure where the folders are that you are talking about. i don’t like WMP because when i rip an unknown cd and then rename each song then try to attach an albulm art to each song, the art goes on every song ripped from that cd even though there are different artist. is there another solution for me to get rid of these dupes unless you dont mind telling me about these folders. u also said not to put them on WMP…where do i put them?
