MHT files can be very conveniently used by webEd to save projects, where all web page coding
and accompanying pictures can be kept together as a single unit.

However, since webEd was written originally, the format of MHT files has changed. This in no way
affects the use of MHTs as webEd projects, but it does mean that the MHT files produced by
webEd can no longer be displayed in Internet Explorer for example, or in Firefox using the UnMHT
extension.
