Clear Dead Links From Your Bookmarks
I'm setting up my new laptop, and plan to copy my bookmarks from the old laptop. Before I copy them, I'll clear out the dead links, to tidy things up a bit. There's no point in copying useless data to the new machine.
If you'd like to do this on your machine, you can use the free utility AM-Deadlink. It finds dead links and duplicate links in your list of browser bookmarks.
It's easy to install and use, and takes only a couple of minutes to check my bookmarks (about 1700). Then I sort the list by error number, and delete any 404 pages.
You can also use AM-Deadlink to create backup files for the bookmarks.
