PART file conversion

I downloaded several files that say "PART" file when I click on Properties, actually *PART is their extension. They are music files, every one is 8:06 min,
, Windows Media Player (and other standart players) is/are able to play them, but other programs don't see them (e. g. when I try to burn a CD), neither does a standard CD player (which normally plays MP3 files). They look/sound like a teaser/trailer, sometimes they start in the middle of a song, or end ubruply.
Is there a way to convert them into MP3 files?
I run Windows XP Pro on Pentium4 PC.

Could you give us a screenshot or possible link us to the source of these files?
