launching on Wintel/inter-process communication

The time stamp seems logical- but here's my question: how does a second 
instance of the application know what file to look for? That is, if the file 
is already there from the first instance which was launched hours ago, how 
can it tell the difference between that file and a crashed one. Without using 
inter-application communication of course =).

Or am I missing something?
