I could not find any documentation about this... at all.
I note that in my registry (Vista x86 SP1) that I do have a ftp protocol handler, but no ftps protocol handler....
I tried search for a ftps protocol but did not find anything that is generic to Windows platforms.
Consider that a suggestion for Windows 7 or an IE 8 sp1 add-on. All Windows machines are initially disadvantaged because there is no supported SFTP or FTPS client, unlike Linux or Mac. Windows NEEDS an FTPS and/or an SFTP client -- standalone or plug-in for IE.
Secure file transfer is a must.
