I warmly recommend adding Everything to that list. It's an instant-results file search tool that indexes your entire hard drive. It lets you find any file instantly.
EDIT: for some extra context, this tool changed the way I name and store files. I hardly ever navigate to a file anymore. I search Everything for, well, everything. After a while, I found myself caring less where I store a file, and more what I name it. I now add any word to a filename that I think I might search it by. Effectively it's a bunch of tags right there in the filename. This removes the need for a separate tagging program like the author suggests.
