-_- Java & C# are not platforms, they're programming languages. I'm making an effort here to understand you, but I don't see how a programming language can relate to the availability of file transfer tools.

Programmatic access is essential in such an environment.

Here's a realistic scenario just to make it clearer. An email appending company lands a big client. The client wants to obtain its customers' email addresses on an ongoing basis. They'll send customer information to the email append company who will then send them back the appended files.

Manually moving files is not an option on either side. What method other than FTP do you suggest here?

OK then, while I don't have much experience with Java and C#, 15 seconds of googling showed me at least one broadly used and well supported, open source library for SSH/SCP for each of these languages. Undoubtedly, there are others that are not free but backed by a real company. This is aside from 'integrating' SCP in the way people 'integrate' FTP - by calling the command line version.

So, whether we define 'platform' as 'OS' or 'programming language', my point stands: name me one (actually used, not VMS) platform for which there is no SCP available.

The availability of SCP is irrelevant. What matters is support. I'm glad you did your research but you came to the wrong conclusion; the conclusion you should have come to is that FTP is much more tightly integrated. In C# it's part of the standard library; in Java it's an Apache library everyone has.

I think you're overvaluing what is the "best" method of file transfer. When you have to set up a file transfer process with a client, and tens or hundreds of thousands of dollars are on the line, you are going to choose the path of least resistance. That path is FTP. Clearly. If you are the much bigger company you have a better chance of doing things the "right way" but that rarely happens just because these are ultimately business decisions and business doesn't care about implementation details unless they cost money.

Most programming environments have SSH/SCP libraries. If you want to maintain a simple upload/download model, SCP is the way to do it.

It's not entirely clear to me that an FTP-style upload/download model is best here, mainly because I haven't the faintest clue what an "email appending company" does.
