Working with Finder
If you have a folder you use frequently, you can save time by creating a shortcut (also called an alias) on the desktop. Instead of navigating to the folder every time you want to use it, you can simply double-click the shortcut and the folder will open. A shortcut will have a small arrow in the lower-left corner of the icon.
If you want to remove some of the clutter from your computer, you can delete files and folders you don't need. This will move them to the Trash (which is just like the Recycle Bin in Windows). Then, if you're sure you want to permanently delete them, you can empty the Trash.
On some Macs, right-clicking may be disabled by default. If you're unable to right-click, you can just click and hold the Trash icon until you see the Empty Trash option.
When you connect a flash drive or external hard drive to your Mac, it is known as mounting the drive. Before you disconnect the drive, it's important to eject it (or unmount it) properly to avoid damaging the data.
If your flash drive appears as an icon on the desktop, right-click the drive icon and select Eject. The drive icon will disappear from the desktop. Alternatively, you can click and drag it to the Trash. It can then be safely disconnected from your computer.
