The Finder allows you to visually access practically everything on your Mac, including applications, hard disks, files, folders, and DVDs. You can use
the Finder to organize all your files and folders as you want, search for stuff anywhere on your Mac, delete things you don't want, and more. To see
your files, click the Finder icon in the Dock, then click "All My Files" in the sidebar.
Finder windows include a sidebar on the left side. Items are grouped into categories: favorites, shared, devices—just like the Source list in iTunes.
The favorite‟s portion contains favorite links to folders which includes Desktop, Documents, Movies, Music, Pictures, AirDrop, and the Applications
folder. The shared portion contains computers that are connected to your computer though the network. The device portion contains mounted and
accessible volumes you have, such as a hard disk, USB flash drive, network volume, DVD, and so forth.
