Flash drives and memory cards are useful storage methods for the transport (sneakernet) of files and pictures. For example, if you have a file or picture that you want to share with someone else, you can save it to a flash drive or memory card.

Select your operating system from the list below and follow the steps for viewing files and folders stored on flash drives and memory cards.

  • If you haven’t already, connect the flash drive to the computer, or insert the memory card in the memory card slot or reader. After a few seconds, a window should open showing the new drive and its contents (A).

  • If a new window doesn’t pop up, you can access the drive by pressing Windows key+E to open File Explorer. Select the drive letter for the flash drive or memory card. The drive letter is usually labeled with the name of the drive’s manufacturer, or similar initials (B). For example, in the image below, the drive is called SDXC because it is an SDXC card from Lexar.
