I had created a project & it kept downloading for several hours.I have
interrupted it now. But it has downloaded a good part of the website I need.

My rules shows as
<http://www.xxx.edu/handouts/webpages/> -O1 "F:\\My Web
Sites\\handouts_webpages" +*.* -ad.doubleclick.net/* -mime:application/foobar

After reading the forum I realised the rule should be
<http://www.xxx.edu/handouts/webpages/> -O1 "F:\\My Web
Sites\\handouts_webpages" <http://www.xxx.edu/handouts/webpages/>+*.*
-ad.doubleclick.net/* -mime:application/foobar

Question:
When I edit the rule to add the filter & re-run the mirroring -
1. Will the files above <http://www.xxx.edu/handouts/webpages/>+*.*  that has
been already downloaded be DELETED?2. I also want to change the path where I
am downloading to something shorter. How do I do it?3. Will be simpler just to
create a new project with a new rule & new path name & run it? 
4. I was thinking maybe create a new project with a new path & rules. Then
move all the files  from <http://www.xxx.edu/handouts/webpages/> & below to my
new directory & run the new mirroring. Will this be faster & cleaner?
