Previous version libraries?

[Bob Clarke 3rd x4502 <clarke@xxxxxxxx>]

I am in the (never-ending) process of trying to clean up some libraries and 
files to free up some disk space.  In doing so I have come across some 'Q' 
libraries whose origin and/or usage is unknown to me.  I did not become 
involved with the AS/400 until around the time we upgraded to V3R1, so I 
don't know if these libraries came to be as a result of the upgrade, were 
just left behind from previous versions, or were created by a former sys 
admin.  Any assistance I can get in identifying these and/or determining 
whether they are necessary would be greatly appreciated.  In looking at them 
and a sampling of last use dates on the files within I am quite sure I can 
safely delete them, but I wanted to check with you folks first.

Library        description (if any)          # objects      type of objects
 ----------         ---------------------------        -------------       -  
 ---------------------

QSYSV2R3M0                    1,752          mostly *CMDs, some PFs.

QSYSV3R0M5                    1,379          mostly *CMDs, some PFs.

QSYS2          System Lib for CPI's          85        mostly *PGMs, some 
LFs.

QSYS38                           597         mostly *CMDs, some *PGMs.


Thanks in advance!!
