I also added this to the IH forums, just to cover my bases.

Thanks for the terrific addon. I won't waste your time. I have B'd-up my site as suggested and have read carefully about not overwriting files. But before I push the IH files to my site via FTP, I wanted to be get some clarity on a something.

If within the IH install .zip, there are files, (.gif's, .jpg's, .php files, css', etc.) that have the very same file name as files currently housed in identical directories on the site, I should move ONLY those files that are different in the IH install .zip to my site?

Naturally, moving identical files over will overwrite what is currently on the site, but I see under the admin/includes/... (purely for example) even images in the IH install .zip are duplicate files names - in some cases - to those on the site.

For instance, does IH need me to upload "icon_xxx.gif" to my site if I already have, in the very same directory, a file named, "icon_xxx.gif?"

This question applies to all duplicate files names I am seeing - not just images. As a matter of fact, icon images are my last concern.

I just don't want to replace even a single file that has a special purpose within my existing site that could be replaced by an IH file that, though named the same, has an entirely different IH-specific function and is thus intended to impact an entirely different string of events.

Thank you in advance.
