cyberark winscp

Dear all as you now winscp has already been installed in cyberark by default. it works pretty well with cyberark. now we want to change External editor from notepad to notepad++. i have made many changes in winscp on PSM server but no success. when i run connection component it returns to its default condition.

I'm sorry, but I do not understand what you ask for.
I do not know what is "PSM server" nor "connection component", let alone what is its "default condition".
