Well, I used WinRar before but suddenly it just disappeared thinking that it might have been because its a free trial.
Ah yeah. It does that if you use the actual program for unzipping. Rather than doing that, once you've got WinRar installed you won't actually have to open the program per se. Instead you just have to right click (if it's a PC you're on anyways) on the file you want to unzip and when the list of options appears you choose "Extract to..." or whatever else option for extracting you feel like using.
