What is special_htm_files folder?

[jimhanus]

I've been updating a site for the past day without any problems. While working on it today I exported it and prepared to upload, and found a folder called special_htm_files next to the index_htm_files folder (.web is called index). This special folder had all the files in it and the index_htm_files folder had one file in it. Anyone know where this came from or why? There's nothing in the file called "special" or named "special". I re-saved and re-exported and now everything is back in the index_htm_files folder as it should be. Just wondering what happened, or should I be concerned?

EDIT: I did find a page called special.htm (oops). Somehow the file was corrupted and my navigation reverted to old links. One page is missing mouse-over effects. Don't really know what happened but it's fixable.
