Windows Vista allows you to easily tag files for improved organization and search. First, open Windows Explorer and find the file you want to tag. The Details Pane shows details associated with the file at the bottom of the window. If the Details Pane isn't turned on, turn it on by going to Organize > Layout > Details Pane.
Click the Tags area of the Details Pane to add a tag. Type your tag, and be sure to click the Save button to save your changes.
Once you tag a file, you can use Vista's instant search to find the file quickly.
