.sfa ???

[Pinguin]

Hi,

I downloaded a divx movie: 11.25.01.EVOLUTION.DVDRIP.DIVX-DOMINION
named: evol-dmn.avi
And there was also another file named: evol-dmn.sfa

Now when downloaded finished,I tried to play that movie, but didn't worked, nor with MicroDVD, ThePlaya, Windows Media Player...
Anything!

So I was wondering if it could be that that other file .sfa had to do something with it...
Are you familiar with this??
thanks in advance for any reaction
