Selecting an application

[Yates, Glen]

This is just plain false, never rely on the existence or non-existence of a
file extension to determine whether a file is executable or not, as files
can be named whatever you want, and changing the name obviously (or perhaps
not so obviously for windows lusers) has no effect on the file itself.

As anecdotal evidence, I have a friend who gives all executable files (apps)
he creates a .x extension to signify (to him) they are executable. I've also
seen .bin, .exe and .app
