Config.Msi

I am using a new desktop computer which is running on Windows XP for quite sometime now. I found a folder on the C: drive called Config.Msi that I think has been empty all the time and which I am quite sure that wasnot there on the pc we just replaced which also had XP. So does anyone know what is this folder exactly used for? Thanks.

Actually Config.msi is the MS installer for office suite and other applications it might be needed when installing a new software or uninstalling a software. Chech the below link for more information:

Its basically a part of an installer for some applications you have installed, you can leave it there as it is.
