well i was writing the code in parts. So i just manually uploaded the zip file...to the server...just so i could test out that the unzip was working fine. Once i got that ok...i would add the file transfer.
This is so basic a need (move a file to server and unzip it in a specified folder), i thought that it was well covered ground...but so far...no one has a solution that works that i have seen.
BUT it is nice to know that i am not as stupid as i thought...or it would have been easy to do. :) Thanks for the interest and suggestions.
