do anyone know where I can download a free program to unzip nds. files my trial period on winzip just ended
WinRar. Windows XP or lower ----- http://www.rarlab.com/rar/wrar393.exe Windows Vista or higher - http://www.rarlab.com/rar/winrar-x64-393.exe
x64 doesn't necessarily mean vista and higher, it depends on your hardware. he should use the first link for pre-caution purposes if he doesn't know if he has a 64bit OS....
winrar is the easiest to get and it doesnt really matter if they say the trial is over it works perfectly fine
