I have created a prediffer which I'm using with WinMerge v (Unicode). I am trying to force WinMerge to always use this prediffer, if possible, for the file types specified (by code) in PluginFileFilters. I have found some things about this in the documentation but I can't seem to find a way to make it work. My prediffer only shows up as a suggested plugin, even though I've set PluginIsAutomatic to True. Is there a way to do this? Configuration? Command line hacks?
