Not sure if this is supposed to work this way, or if means anything.
While looking for some files using BBedit 13.5 I notice that all of my Panx files had triangles before them, which if I clicked, dropped down and listed the application files (settings.plist,.data.plist, etc.) and .archives files. Tried it at home with Bbedit 9 and did not get the dropdown list, but when I clicked on the file, got data.plist and setting.plist in a view menu.
I have no idea if this is useful or dangerous, but thought I’d pass it along.
