But

Answer 1

We have had issues under Windows 7 with UAC and unexpected file permissions. File#canWrite will return true even though any attempts to perform file I/O will fail.

1. Make sure the file you are trying to rename actually exists
2. Make sure that the location you are attempting to write the file (or rename the file) to is accessible. We write a simple text file to the location, check to see if it exists and that it's contents is correct (we're paranoid) before we attempt any further I/O.
