Finishing create file logic, and starting printing a directory, which doesn't work.
Errata:
- Checking if the bit is set in the chunk of data in the parent directory, should have _not_ as the if condition. If the bit is NOT set. Currently it checks if the bit _is_ set, and goes to use that bit, which is wrong!
- Other things I forgot but are probably wrong
