Safe to delete Config.msi ?

[ozqadir]

Hi Guys,

I'm tidying up my XP R51 and have come across a config.msi file.

This file contains 2 files which are both .rbf and both >1GB!

I heard these are rollback files for MS Office 2000 (I have Office 2003).

I've been surfing the web for a few days now but can't seem to see the consensus about if it's ok or not to delete.

Can anyone help?
Thanks in advance!
