Classic Find is inspired by the Find File utility seen in Mac OS 8 through OS X 10.3. It features a list of all attached drives/volumes where to search upon. You can choose to search one, all, or only a select few drives. This is useful for cutting your search time down, or when you know you only need to search certain disks. Especially helpful in networked environments where you really don`t want to search all connected volumes. Classic Find uses the Spotlight search engine for default searches, so your volumes should be able to be searched by Spotlight. You can use the File Search function to search all files individually on a disk, but this is much much slower. But unlike Spotlight which excludes certain directories from its index (like the System and Library folders), File Search will look at everything. But it can be slow. Once found, you can highlight a found item in the Found Items window, and the lower info panel will give you more details. In the list, double click the name of a file to open it in the default application for that file, or double click the file path to open that folder and see the file on disk.
