Of course i could, but that would ruin the fun.
The main reason why i'm trying to get this work is because i store these on a fileserver.
To unzip them i have to copy them to my computer, unzip/rar them and then copy it back onto the fileserver. Unraring on the fileserver isn't an option, because it's a pretty old computer so it would take a long time on larger archives.
I've got the shares mounted on my comp. using samba, but unraring through LAN is slow, too.
