ISO invisible after 7zip.

So, I got a new laptop and decided to see how well it could run PS2 games. Thing is, I can't even get that far. I'm getting this weird problem where, after I unzip a PS2 game using 7zip (they're 7zip compressed), the uncompressed file becomes invisible to Windows and other Windows based programs. 7zip says it's there, just nothing else can see it. I've tried using a different game, thinking I might have gotten a dud, and got the same thing. 7zip didn't have this issue when unzipping the bios, just PS2 games. I'm in the process of getting a PSX game to try it out on, all my others are still stuck on my old (dead) computer for now. I'm on Widows 8.

Anyone have any idea what the deal is? I'm baffled.

Thanks.

Seems like it can find it after I dragged it out of programs and into Desktop and made it extract the files there. Wow. Windows 8 never ceases to disappoint me. I'm not sure what happened there. I have several gigs of invisible files in programs to clean up now. -.-

Erm, when you say "invisible to windows", do you mean you can't see the extracted files at all in explorer? There's no reason windows should be doing this under normal circumstances. Have you double checked where you were extracting said files in the first place?
