Is it possible to crack a .rar or .zip file?

I mean really is it impossible to crack a protected password file with 5 letters? REALLY? Would it take years to crack with brute-force...? We crack windows, games but not a .rar file?

It depend which CPU (and GPU sometimes) it can take minutes like hours.

It's possible with a Brut force attack, but the program eats a lot of the computer, just with a good computer and a lot of time you will can...
