In our case, long ago we used an extension - "cfg" - that's unfortunately very common. We changed it before we ever had a Mac app, so the only "cfg" files on a Mac are either very old and copied from another OS, or should be opened by some other app. The handful of people who do have old files are happy enough with having to go through File->Open and the vast number of other people are happy that double-clicking their "cfg" files doesn't open our app. That's why I don't know about the save options - we don't save this format :)_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
