I have an older site that has gone through some revisions in the last few years and it has a lot of orphan files, I am trying to clean it up and I would like to get rid of the orphan files. It is a very large site, getting rid of the orphans will reduce it in size by about 20% or more. My page rank is currently a 5 and I'd hate to lose it or be penalized for the reduction in size. Any feedback or advice as to how this could harm my google status and page rank would be greatly appreciated. Thank you.
