Rewrote findfile to store whether any of the three paths searched had a bad MD5 rather than just simply being not there. 

This means that, if the three paths are not the same, you should be able to tell if at least one of them has a file that just had a bad MD5. Most relevant for Linux peeps I expect.

Note: Untested as of writing
