Site Cache

I just reinstalled my operating system and applications. My site folders are
present in the site cache folder under Documents and settings\my user name, but
they are not taken up by DreamWeaver's list of sites. What can I do to bring
them along, short of recreating them all? As a test, I created a new site, and
it showed up in the same folder. But the others are not recognized. tks, jwc
