usage of dropfolder

[Bob Sneidar]

I believe that OS X creates a placeholder file while the "real" file is being copied/worked with. I am not sure what the method would be to determine if the process has completed yet. I suspect there is some kind of flag on the file itself, read only or a file type reserved for this sort of thing. 

Oddly, this allows you to actually rename a file WHILE IT'S BEING COPIED. You may be able to do other things as well. Isn't UNIX wonderful?
