I'm sort of new to sfv files but i recently downloaded a game and i got all the files and there's this one sfv file and i was wondering how do you extract the files out of it cause i have tried winrar and winace but there not the right type of programs. i also found alot of other programs but all they seem to do is verify the files and the files are ok. i just need to know how to extract them.

any help is appriciated. thank you.
