Associating .ndg File Extension With Netpad.exe

Aternatively the association may be set up as follows:

Select Advanced and add an "open" action if not already present.
Edit and ensure Action is set to "open" and Application used to perform action is set to "C:\Program Files\Network Notepad\netpad.exe" %1
(Or path to where Network Notepad is installed on your system).
