'Zen Folders', and 'Samurize'

Zen Folders

zenFolders are virtual folders that do all of your searching and organizing for you. Utilizing Google Desktop Search, zenFolders dynamically generate content from your search results, collecting all of the relevant files into one convenient place. These folders don't really exist on your computer -- they only appear as folders. But anything that has to do with your topic is brought together with just one click.
