This article explains how to format external USB drives in Windows 11. We’ll walk you through each step so you can prepare your drive for backups or file storage.
Why Format a USB Drive?
Before you use an external drive in Windows 11, you may need to format it. Different operating systems use different file systems. A new USB drive usually works right away on Windows computers. But if it came from another operating system or is used, you might need to reformat it first.
What happens when you format a drive? Formatting prepares your drive to work with Windows. It also erases everything on the drive, so make sure you back up any files you want to keep.
