When I took that same project and altered the setting to Local PC or Intranet (Internal Network), I found the same files listing the index. Unfortunately, this likely isn't the best of tests, as there really aren't enough Index entries to be representative of a real situation. But in the past, I saw as many as 90 or so different XML files that composed the Index. That was using the "Web Site (Internet) setting. I'm not sure how many files would have been present had I selected the Local PC option.
thanks for the response Rick. So you're saying it could be any number of files in the whdata, whgdata or whxdata folders that get created when compiling?
I just assumed it would be a single file like the .hhk file in the project folder.
That's precisely what Rick means.
