FTP?

That functionality isn't available today, but we may add it in the future.  Please vote on this user story if this is important to you:

There are some other features we may add sooner that could also help with FTP, though:

https://trello.com/card/5-open-from-command-line/4f90a6d98f77505d7940ce88/349 -- Launch Edge Code directly from the command line (with parameters), which may allow you to link Edge Code to a third party FTP tool as your default editor.

https://trello.com/card/shell-out-to-external-tools-scripts/4f90a6d98f77505d7940ce88/625 -- Launch other tools or scripts (such as an FTP upload command) via a shortcut within Edge Code.

Hope that helps,

- Peter
