@scragarFeb 13.2008 — #there must be command line unzip programs for windows, and the exec function should work on windows(although I've never tried it). Only thing I can suggest is to go search google or something.
sorry.
oh, and exec() runs parallel to PHP, so running unzip might take a while to complete, even after the page has finished being processed, if you want anything in it look into logging something into a text file and reading it (or even just using filesize to check for size changes).
