Yes, RT-11 is a somewhat unusual file system in
that it doesn't just
support contiguous files -- it supports ONLY contiguous files.? That
makes for a very small and very fast file system.
The only other example I know of that does this is the PLATO file system.
The UCSD P-System had contiguous files.? If small files had been
deleted, so that space was fragmented, you had to run a "CRUNCH" program
to defragment it.?? Directory entries had the starting location and length.
