File Sizes and Types

The UNIX file traces referred to in the previous section have also shown that the average file size is less than 10K, and that there are distinct file types and classes.

I do not know if these traces are out-dated. Nowadays most systems have some sorts of multimedia including high-resolution pictures (e.g., JPEGs & GIFs with sizes from 20K to 300K) and movies (e.g., MPEGs & MOVs with sizes from 500K to many MB), and what about a future with generalized objects in an object oriented (OO) world?

Still, I will not make any efforts to support large files nor different types; at first my system should be used for reading e-mails, newsgroups, working on reports, etc. No multimedia for now!

The Odyssey system is an example of a system that tries to integrate different consistency requirements according to the filetype using a notion of fidelity, see [43].
