Oh, you should be able to do so with any extraction file system, like winrar. I'd look up a tutorial online there's probably some much better ones than I could do. Should be able to do it fairly easily and free.
Hi Samae & PixelWestern! An additional piece of what I think is awesome software that can open such files as well is 7-Zip, for anyone looking for an alt! ;) Cheers! ~K.C.
