Need help with ePSXe

hello ive downloaded ePSXe and follwed all the instructions posted in sticky i got a ps1 file which is sfa3.7z.002 street fighter alpha, now how do i play this file ??

Well first off im guessing you dont know thats a .7z file you will need to
download 7-zip.

Then where ever you downloaded that .002 file you will need to get the .001
in order to extract the game. .001, .002 and so on are zipped archives that
are linked to eachother much like .rar's part 1, part 2 and so on.
