I just installed 2011 to my USB HD and would like to check if there are duplicate files that I may now have. I am thinking that I may have some duplicate RT/RD files. I never received a "do you want to replace" option during installation. But, I may have installed one or two of the .EXE files twice. Not sure?

1. Is there a way to check these?
2. Does Biab have a procedure of removing them?

Thanks for any advice.
