I've found a way to upload complex documents such as web pages with
multiple graphics. There has long been a windows setting that
combines an html page such as Example.html with a resource folder
for it with the same name + _files behind it - thus the resource
folder would be named Example_files.

If I upload a new document to a Document Library and use the upload
multiple files option, I can select the Example.html file, and the
system will prompt me to make sure I want to upload all the files in
the resource folder. The page continues to work in SharePoint, but
SharePoint will not show this folder to users through the browser.
You can however view it through webdav or FrontPage. Any ideas what
is stoppping this folder from being viewable in the browser? Is
this an acceptable way to put these complex documents into
SharePoint if you are unable to see the folder?
