The new search feature in Windows Vista integrates itself entirely into the operating system. All one would have to do is click 'Start' and type in a file or folder name and it will displayed accordingly in the menu. This eliminates the need to use the 'Search' dialog box. But at times you may wonder why a file is not displayed in the search results even though you are sure it is on your system. This is because not all directories and paths are indexed by default. To add a directory to the index:

Click 'Start' and type 'index' in the 'Search' box.

Click the 'Modify' button.

Click 'Show all locations' and select an appropriate file or folder.
