Hi Unclebill,
There are lots of fake & misnamed files around, always use Bitzi to check a file before download. People use Bitzi to rate files...if the file's been rated then you'll get an idea of content & quality. See the 'how to use Bitzi' link for info about downloading
Bitcollider...so that you can rate files yourself.
If a file has heaps of sources but no Bitzi rating, chances are it's a fake. There's more info & tips in the threads below.
