Ted is correct using mere Zip compression with a password. That is why I stepped up to WinZip Pro, and use its Zip with encryption - which goes beyond just a password protected Zip file approach. They have a few add-on so one can use a Command Line Interface, and a fee based add-on that creates a Self Extracting Zip file. I use the Command Line Interface with Encryption/Decryption to automate a series of scheduled ftp uploads & downloads between my machinery and client machinery throughout the US. Very consistent and stable solution.
