Need help with .bin files

Well i need help working with these .bin files. I just downloaded Mass Effect 2 yesterday and it was a 4gb iso file. I extracted the iso file and now i have two bin files named data-a and data-b. I tried to mount them with various programs like poweriso, magiciso, daemon tools but none of them work. Can anyone help me to get this to work? Maybe some kind of tutorial. Thanks.
Answer #1
Why dont you try mounting the ISO, instead of extracting it?
Answer #2
LOL can’t believe i didn’t do that, thanks it worked.
Answer #3
You’re welcome, mate. Cheers…
