Problem finding songs on computer

It seems that songs I downloaded onto my Sansa m240 only show up when I open up the folder on the computer that the songs came from. For example, most of the songs were downloaded onto it from my boyfriend’s computer, and when I try to use my laptop to look for the songs, I can’t find them. I know they’re there!! Does anyone know how I can find them?


Menu < Settings < USB < MSC (or MTP)
