Re: Random access to content of archived files without extraction - how? compression

Come to think of it better compression would be achieved if the sectors
were fuctionally mapped, and no sector indirection information had to
be stored.

I'm sure the "occupied" or sectors with too small a capacity for
certain data could be considered relatively bad or virtually allocated.

This would present the grand trade off between speed and size of 2
virtual sector algorithm indicators per real sector used for virtual
sector storage. Highly compressable data could be held in nested
virtual sectors with "real" sector numbers exceeding mapping to real
sectors. ( this at 4 virtual sector algorithm indicators per real
sector, stored in virtual sectors.)

this is an easy functional mapping

the virtual sector algorithm indicators should be stored hash table
fashion ? or is that too much given away?

cheers
