Well what I'm trying to do is be able to edit the mirrored site in Dreamweaver.
The only info I could find is this:

Q: Can I convert a local website (file:// links) to a standard website?A: Yes.
Just start from the top index (example: <file://C:\foopages\index.html>) and
mirror the local website. HTTrack will convert all file:// links to relative
ones. 

...and that is what I have been trying to do.
