Flash drives are small removable hard drives that plug into the USB ports on your computer. Flash drives make it easy to carry your photos in a portable form.
Here is mine for you.
To connect a flash drive:
Insert the flash drive into a USB port on your computer. You should find a USB port on the front, back, or side of your computer (the location may vary depending on whether you have a desktop or laptop).
If you're using Windows, a dialog box may appear. If it does, select Open folder to view files. On a Mac, aflash drive icon will usually appear on the desktop.
