Notes
- Only accept explicit filenames (wildcard are not allowed).
- However if a RAM device is not specified, it will automatically be included (the current) into the directory name.
- The buffer of the directory name must have space enough to get itself expanded with a device name (additional 6 bytes).
- The filename must be terminated by a control character, eg. null (0) or CR (13).
