What is the way to use FTP and Notepad++ (without using its build-in FTP or a FTP client like FileZilla)?

"Here is my ""Notepad++ FTP best solution""
I use WinSCP and set NP++ as a default editor. When I open a connection in WinSCP, select a file and hit F4 the file is opened in WINDOWS\Temp with NP++, when I save that file WinSCP automatically uploads it back to server. Works like a charm! WinSCP is the most stable thing I ever tried, it never looses a connection.
FTP_synchronize sucks. Manual upload is not handy. So WinSCP+NP++ is the best solution.
Give it a try."

Does it have to be built into Notepad++? If no, I'd check out ExpanDrive.

"I use FileZilla for FTP. You'd be hard-pressed to find any plugin that beats it.

You can kind of ""synchronize"" with Notepad++ by setting it as the default editor in the settings then doing right click > edit on the server-side panel."
