I downloaded a file and it wont play on my MP3 player?
Most MP3 files on public servers are named with strange extensions or are not descriptive to what file type they are. If you already tried renaming the extension of the file to .MP3 and it wont play it may be a COMPRESSED ARCHIVE file in various formats. Of which the most popular is obviously WINZIP. Try renaming to .ZIP and open the file in WinZip. There are other COMPRESSED formats and some have password encryption so you may need a password. In most cases we provide the password if we know it but 99% of the time the file is either an MP3 file or a WinZip file. One other occasionally used format is self-extracting archive. Try renaming to .exe and running it (BE CAREFUL SCAN FOR VIRUSES).
