One of my colleagues could come up with a sensible use case for
"File_Missing": When a web service wants to know if it should ask a user
to upload a profile image (stored in a file).
Some applications use the existence of certain files as a simple
external management interface. Although I consider this bad style and
prefer a socket based management interface, it might be considered a
reasonable use as well.
Can anybody supply some other sensible use cases for
File_Exists/File_Missing.
Greetings,
Jacob
