>>WinInet doesn't support SFTP... so that's the end of that story. I don't think it'll ever be added either since WinInet is a no longer updated technology. I think the only piece in the Microsoft stack that does SFTP is the .NET components - none of the native Windows components do last time I checked.

>>I recently started implementing an update to wwFTP that uses the .NET components and it will include SFTP support in several of my products. SFTP support seems to be a request that comes up a lot, but unfortunately currently I don't have support for that particular tech out of the box :-(.

>I had to deal with that recently. Even at the .NET level, WebFTPRequest() does not support SFTP. So, are you using a third party? If yes, I would like to know about it. I started to check some out there but they are all between 340.00$ and 350.00$. I found one or two that are free but they do not offer that much and it would be a total waste of time to try to negotiate with such a tool.

.NET 4.0 includes SFTP support...
