From the developer: "Check Favorites is a complete solution for maintaining links in your Favorites list. Check Favorites can check multiple links simultaneously and optionally can remove all of the broken links for you. Check Favorites also supports the ability to export your Favorites in a variety of formats, as well as the ability to extract, check, and export the links contained on any HTML page on your system, or accessible via the Internet. Checking the links on a page on the Internet can be accomplished using Internet Explorer, through the use of a custom Protocol Handler."
