CDS_LIB: contains all the libraries that are you used for the schematic. all these libraries might be using each other in for the top level layout.
cds.init : Cadence internal or users custom files ( user defined cadence .il files) which are uploaded when one invokes cadence.
There is a libManager.log : which contains all the things you do with manipulating the libraries
cds.log : all the commands that are executed on the cadence CIW window
display.drf : contains the color code and other information for the layers in layout
I am not sure what are you looking for...as most of these files are setup by the CAD team and designers dont need know much about it
