When i add both an Address Book and iCal backup files (.ABBU and .ICBU) the name gets changed to -1 or -2 and shows up as a folder with contents inside it. I guess the type is getting stripped or something. Anyone have an idea how to workaround or if I am doing something wrong. For now I am making an archive of file, but it is a bit of extra hassle.
PS I am a paying customer finally! I tried Yojimbo again, just to be anally thorough, and it really doesn't have close to great features that EF does.
