Powermarks
For those of you who are frequent users of your Favorites /Bookmarks,
the previously-mentioned backup tips are absolutely essential, but if you REALLY like maintaining a significant bookmark collection you may wish to consider a program that I absolutely love to pieces called PowerMarks

I have been using it for about five years and in my humble opinion it blows away the other bookmark manager utilities for a variety of reasons:
1. It dispenses with the Windows "folders" approach to categorizing and organizing your bookmarks. Instead, it allows an unlimited number of custom keywords to describe any given bookmark, and it searches the keywords in lightning speed even on a slow computer.
How often to you ask yourself "What folder should I put this bookmark in?" Websites are oftentimes quite varied in their content or focus and as such are difficult to define to the point of being able to realistically put it in only one folder. So, do you save multiple copies of the same URL in different folders, or do you have one massive "Miscellaneous" folder with six thousand entries in it? Either way, it's terribly inefficient and oftentimes impossible to deal with when you are trying to find a specific bookmark that you've saved.
2. It checks the pages for you. How often have you saved a bookmark and then six months later you go back to it and you get an error? Web pages change, and Powermarks will continually update it's listings with a wide range of automatic or manual functionality.
3. It's simple to back up. You can quickly backup your bookmarks in a variety of file formats to any folder or drive that you choose. The developer even offers free accounts that allow you to backup your bookmarks online.
4. It's simple to add a bookmark. Powermarks allows you the option of adding toolbar buttons to your browser that allow simple one-click adding of bookmarks which use the website's keywords, or you can also elect to customize the keywords yourself for easier access later.
5. It's simple to import your existing Favorites. It has a simple dropdown menu that gives you import options, including the option to automatically import your browser favorites whenever you start Powermarks.
Powermarks has many, many more features than the few that I've mentioned, and I hope that people who like to use their bookmarks a lot will give it a try. It makes everything pertaining to the bookmarking issue quite a bit easier than the native tools provided by Microsoft.
