I am using WinSCP with Notepad++. I tried everything I read in the FAQ and the forum.
Operation to perform on double-click is Edit. I checked external editor opens multiple files in one window.
When I doubleclick a file, it transfers to the TEMP directory. When I save the file, it saves in the TEMP directory, but doesn't upload the file. The internal editor is ok, but I need Notepad++'s features.
WinSCP version is 3.8.1, Notepad++ version is 3.7
