It's not local. It is a global variable. It is defined outside
of any of the functions.

Why not? What is so different between that path and the one in
the code below?

No, there are functions for manipulating paths that should be able
to do that for you without resrting to regular expressions.
And those functions should be platform independant too!

This is where trashcan is defined.

THis uses the definition above...
