Retrieving hard disk space

[Antonio Querubin]

I just installed an update to AIX 1.2 on a PS/2 and seem to have lost well
over 10 megabytes of precious disk space in the process.  Seems that there are
some big files in /usr/lpp.save.

Just how necessary is it to keep these files around, especially if
I don't (or can't) uninstall anything?  Incidentally, why doesn't uninst work 
like the manual says it's supposed to?

If I can get rid of some of these files, which ones can I dump safely without 
jeapardizing future installp's and updatep's?  Are there other obscure files
that I should target for removal?  

Would appreciate any help on this as I am running very low on disk space.
