Yup, I know.
But hey, programmers are used to working hard. :-)

When your dealing with an API without interfaces you just /have/
to work hard to break dependencies.

Luckily, File and it's methods are not 'final'.
So another possibility is to subclass File and over-ride the methods  
you are
interested in on a test-by-test basis.   (this technique is often  
called a "shunt").
Inner classes can be used for creating the shunt.

If your only using a few File methods over-riding is a good enough  
option.
But then you still have to build an injection mechanizum to get the  
shunted File
from the test into the target.
