No, that was the first thing that I checked. I was 99.99% sure I didn't change the name of my index page, but I looked anyway to play is safe.

When I go into my webroot folder via FTP, I can verify that my entire index_htm_files folder is missing. (And that it has not been replaced by another _htm_files folder of a different name.

I don't get why the program would delete my entire graphics sub-folder, when it should obviously know that all of the graphics on my pages are linked to that folder.
