Thanks for the reply.
It would appear to be an issue with the PowerShell module as when I use the put command it works fine and when I manually transfer the files that also works fine.

You are using WinSCP PowerShell module. That's a 3rd party package. We do not maintain it.

Though, I cannot imagine that the module would convert the filename case on its own. Maybe it's a "feature" of your server. Did you test this in WinSCP GUI? Or with WinSCP .NET assembly?

Hi,
In PowerShell I am having issues with the Send-WinSCPItem not preserving the filename case of a file I'm uploading to a remote SFTP server. Not sure if it's my stupidity....?

So, if $localfile contains say D:\Test\MYFILE

when I run the following

When I check the remote server the filename has been changed to lowercase i.e. myfile instead of MYFILE.

Is there some session option to preserve the case of the file that I'm missing?
