Identify if additional directories can be created. This may indicate that directories are not available to this operating system or simply that the disk image is "locked" to writing.

Specified by:

Indicates if this disk image can create a file. If not, the reason may be as simple as it has not been implemented to something specific about the disk.

Specified by:

                               throws DiskFullException
