A USB flash drive is a portable hard drive that allows you to store files so you can upload them to another computer or device. Flash drives vary in memory size anywhere from 128MB to 4GB and more. They are also a convenient way of backing up files. Uploading pictures from your computer to a flash drive is simple for both Windows and Mac operating systems.
Plug your USB flash drive into an open USB port on your computer. Depending on your computer, USB ports are located on either the back or front of your computer. On many laptop models, USB ports are located on the left or right.
Launch "File Explorer" using the Windows Search charm. Your flash drive should appear under the Computer heading on the left side of the File Explorer window. For Mac users, the flash drive is displayed on the desktop.
Double-click your flash drive to open it. Locate your pictures from the folders where you have them on your computer and select the pictures you want to upload to your flash drive. To select several pictures, press and hold "Ctrl" as you click each image. For Mac users, hold "Command." Right-click the selection and click "Copy."
Go back to the flash drive window you launched and right-click an empty spot. Click "Paste" to copy the pictures to your flash drive. You may also drag the photos to the flash drive window.
Close the flash drive after the copying is complete. Click the "Safely remove hardware" button on the system tray by the clock and click your flash drive's assigned letter in the "Hardware" window. Click "Stop." When prompted, remove your flash drive from the computer. For Mac users, drag the flash drive from the desktop to the recycle bin. Remove your flash drive from the computer.
