Mac OS X 10.4 Tiger features Spotlight, a lightning-fast search technology that instantly lets you find things on your Mac. By default, Spotlight will index and search in the following locations:
Can Spotlight search anywhere else? Of course! Any new folder you create in your Home automatically gets indexed so that it's searchable. If you connect an external storage device, such as a USB or FireWire hard drive, Spotlight will index the stuff on it, too. (If you want to exclude certain areas from Spotlight searching, see the tip below.)
Note: If your computer has multiple user accounts, any files that reside at the top level of each user's Home folder will also be indexed and searchable by Spotlight, even though they cannot be modified. However, all files and folders located within a user's Desktop, Documents, Library, Music, Movies, and Pictures folders will not be indexed nor can they be searched by other user accounts using Spotlight.
Tip: You can use Spotlight preferences to tell Spotlight which locations not to search, if you wish.
