When I used AS4, I was able to use Notepad++ to edit mpalarmxcore.
However, in AS6, I can’t seem to find that option anymore.
On my old laptop, my predecessor had set it up, so I don’t know what configuration was used.
as alternative editor, for textual information Automation Studio always offers the Windows Standard App that is associated with the file type. If there’s no association for the filetype (yet), there’s no alternative available.
That means: to open mapp configuration files externally in Notepad++, you have to associate the filetypes in Windows with Notepad++.
The’re different ways how to do that depending on the Windows version you use.
Here’s one example associating the file type .mprecipexml with Notepad++ via rightclick in WIndows explorer (sorry for the german screenshot, but I think it’s nevertheless helpful):
in Windows explorer, rightclick a file of the type to associate
find the suitable application you want to associate with in the list (if it’s not listed, find the “search” entry in the list and navigate to the app)
After association, you’ll see the icon of the files of that type is changing in Windows explorer.
And: now it’s also available in Automation Studio via rightclick → open
