IBM Objects ending in X

When I'm working on something I like to save the old library first by
copying it and adding an X at the end.

While cleaning up my system today, I ran across 3 libraries:

QWEBQRYX
QCTX
QDNSX

They were created in 2016 and haven't been touched since. Says created by
user QLPINSTALL.

Should I leave them be or can I remove these? Seems like maybe temp
objects for the real libraries during an install/update.
