PutFiles methods were introduced to FTP in version 3.0.3300.0 at 2009-01-14.
To download the latest version just login to rebex.net/protected and download the latest version. If your company have a valid support contract you'll be able to download the latest version immediately. If your support contract has already expired you'll see a link for support contract renewal. The renewal cost is now about 1/3 of full license price per year. Or contact firstname.lastname@example.org for help.
Alternatively, you can use a combination of
PutFile methods to implement multi-file download - check out the source code of the
ConsoleClient sample (
PutDir methods) for a sample implementation.
