What is a .apple extension? I am recovering some files and I recovered several files with the .apple extension.

(1) Are the filenames familiar? How about full name examples? (2) I added the file-extension tag, and removed the mac tag due to being implicitly obvious. (3) Which version of OS X are we talking about? – Jason Salaz Aug 4 '11 at 19:10

Winner winner chicken dinner! - see the wikipedia article linked above. The free stuffit on the app store should unpack it for you (assuming it's not corrupt or the orphaned second half of the main file) Also RFC1740 ( should put you to sleep reading about this format. – bmike Aug 4 '11 at 21:26
I opened them with Stuffit Expander, but nothing happened. – daviesgeek Aug 4 '11 at 21:32
