Flash drives, also known as pen drives or USB drives
, allow you to carry data easily in a portable storage unit. If you’re unable to access or view files and folders
on your flash drive, there are a few common errors that ma be causing the issue. For example, you might have inserted your USB drive and can see that space is taken, but no files appear.
