Can i get some links to or get an explanation of unziping a file with VB. I would like to create a kinda mini installer that unzips a ".data" file which would act like a zip file. The .data file would really be a .zip file but so that nobody doesnt just open winzip to unzip it i would rename it to .data . How would this work? Can VB unzip files? I've seen programs that unzip in vb.
