Lifehacker linked to a neat program today called Explorer Breadcrumbs. After you install this program, a new Breadcrumb Bar sits at the top of the explorer window and gives you an easy way to navigate quickly throughout your file system. The bar lists all of the folders above the one you’re looking at in the file system, so you can jump back to any point you were at before.
This is actually a feature of Windows Vista, but this program allows Windows XP users to enjoy it as well.
I’ve recorded a quick video to demonstrate how it works.
