There are a number of parity issues with the implementation of Ti.Filesystem.File#getDirectoryListing() on Windows, which can be seen in the tests now skipped there:
- calling it for a file should return null
- calling for a directory that does not exist should return null (returns empty array right now)
The other test ("can access resource directory files") may be failing due to Windows not appending a trailing separator while other platforms do? I tried with unix and windows separators and that didn't seem to fix it, so I don't think it's a separator mismatch issue.
