How to save all search engine results urls in a text file
 

From this search engine:

https://siteexplorer.search.yahoo.com/mysites

when I make all subdomains search just by typing a domain url in a search box like
blogspot.com -and after I verify my yahoo email password I get 28 millions webpages listed on thousands of search result pages.I want to save the all urls and again only the one that have flv files in a text file so some flash downloader preferably freeware could preview or download them selectively or all.And can interrupt it use what was saved and finish if I like anytime.
