USB drives can come in different shapes and sizes. You could have a flash drive that fits in your pocket or you could have an external hard drive the size of a book. Either way, the USB drives are used for extra storage of file folders and other media. The protection of that media is important. USB drives do not come with protection; you have to set it yourself. Putting a password on your files is not a hard task and will not take long.
Turn your computer on and wait for the Windows Login screen to appear. Enter your login information into the boxes and log into your system.

Double click on your USB drive's icon. Right click on an open space in your USB drive's window. Create a new folder by clicking on the "New Folder" option in the menu that appears.
Drag all of the USB drive's contents into the new folder that you created. Right click on the new folder and click on the "Properties" tab. Click on the "Sharing" tab in the Properties window.
