Rob,

  I dont know if you can permenantly delete them. I beleive that you
will run into trouble.  THis files get full of deleted records, and you
need to bring the system into a restricted state to reorg them using an
IBM program by doing CALL QDBRCLXR or for those on V4R2 RCLSTG 
SELECT(*DBXREF).  Everytime you do a restore, rename, create of files
this cross reference files get updated.  THis functionality was added to
all OS/400 levels starting with V3R1.

  I dont know why you have the SSA *USRPRF in that list above. If you
are wondering why it is so big, it because it probably owns all your
BPCS objects.
