If you test the Zip file before uploading it to an FTP server and no errors are reported, but after uploading the Zip file is damaged, the behavior is likely to be due to corruption of the Zip file during the file transfer. Please note that when transferring via FTP, the binary mode must be used; a text or ASCII transfer will always result in corruption of a Zip file.
