what file extension do i use with nskeyedarchiver

Question

I am writing an app that uses NSKeyedArchiver to save its data. Should my file be ishotTrack.plist or ishotTrack.arch?

Answer 1

The archives created with NSKeyedArchiver are binary property lists, so it makes sense to use plist file name extension. On the other hand they aren't human-readable, so opening the plist won't help anybody much.
