Last I checked some years ago, the RT-11 file system had the following deficiencies: (a) it was not hierarchical, i.e., no subdirectories; (b) it forced files to be contiguous, so you easily ran out of space for a file to grow even if there was plenty of free space on disk. It's easy to design a file system with such defects and make it fast. But that has nothing to do with UNIX or MS-DOS. -- Rahul Dhesi UUCP:!{iuvax,pur-ee,uunet}!bsu-cs!dhesi
