Locating files with tags

To tag a file, right-click it, and then choose Properties, go to the Details tab, and you can add a tag from there if you click on the Tags section (under Description) under the Value section.  Just type it in. When searching, you can then use those tags, such as you could tag a few files as a particular work project, all of which would come up when you searched for that term at a later date.
