Validate path - Dave Dunfield - Feb 01 2010

is not zero-length and has the correct length for it's directory entry.
Also checks for directories containing nothing.

Useful for a quick check of copied media etc.

Opts:   /C      - inhibit "Can't open" error.
        /S      - inhibit "Size mismatch" error.
        /N      - inhibit "No files" error.
        /Z      = inhibit "Zero length" error.

While scanning, press SPACE to skip current file, ESC to stop.
