Hi -
The experts in Derby internal processing are on the derby-dev maillist - 
this list handles usage questions but here are some very basic answers.

Derby utilizes java.io methods for writing in order to be platform 
independent.  The developers can talk to which ones and why if this is 
of interest.

The Derby data files are found in in the 'seg0' subdirectory of the 
database directory.  There is one c*.dat file for each table and index 
(c stands for Conglomerate).
