Click the Finder app icon, which resembles a blue face, in your Mac's Dock. Open a folder when you keep your files, then click and drag your mouse cursor across the contents of the folder.  You can also hold down ⌘ Command and click each file you want to copy to select them individually. If you can't find your files, click All My Files on the left side of the Finder window to browse all of your Mac's folders. It's in the upper-left corner of your Mac's screen. This option is in the Edit drop-down menu. You'll find it below the "Devices" heading on the left side of the Finder window. Doing so opens your hard drive's window in the Finder. If you can't find your external hard drive here, try using a different USB slot for your hard drive. The drop-down menu will reappear. This will begin copying your selected files onto your external drive. Depending on your files' sizes, this process time will vary. It's an upward-facing arrow to the right of your hard drive's name in Finder. Doing so ensures that you can remove your hard drive without risking file loss or corruption. Once you see the external hard drive's name disappear from the Finder side pane, you can physically disconnect it from your Mac.
