How to Partition USB Drive in Windows 10 & 11 (Create Partitions in USB Drive)

You can partition the USB drive in Windows for better data storage and management. Follow these steps to create partitions in the USB drive.

In general, almost every one of us uses partitions so that one big hard drive turns into multiple smaller drives. This allows us to better manage our data by putting it in various folders and drives. However, when it comes to USB drives, we use them with one partition, no matter the size. For the most part, this is not an issue. However, if you have a big USB drive and want to use it for multiple purposes, is it not better if it can act like multiple drives?

For instance, you can install a bootable OS in one partition and use other partitions for data storage. Thankfully, you can easily partition the USB drive in Windows using a built-in tool. Let me show you how.

Caution: To partition a USB drive, we need to format the drive. So, back up any data in it to a safe location.

Before creating partitions in a USB drive, make sure that it is plugged into your system and has no data in them. The partitioning process will delete all data irrecoverable.

  1. Press the Start key on your keyboard.
  2. Search and open “Create and format hard disk partitions.”
  3. Find the USB drive in the Disk Management window.
  4. Right-click on the drive.
  5. Choose the “Delete Volume” option.
  6. Press the “Yes” button to confirm.
  7. The USB drive is marked as “Unallocated.
  8. Right-click on the unallocated USB drive.
  9. Choose the “New Simple Volume” button.
  10. Click “Next.”
  11. Type space in MBs in the “Simple Volume Size in MB” field.
  12. Press “Next” to continue.
  13. (Optional) Choose a drive letter and press “Next.”
  14. Choose a file system and click “Next.”
  15. Press “Finish.”
  16. With that, you created a new partition in the USB drive.
  17. Follow steps 8 to 14 to create another USB partition.
  18. Once done, close the Disk Management tool.
  19. You will see the new partitions in the File Explorer.
  20. With that, you created two or more partitions in the USB drive.

Right-click on the USB drive and select Delete Volume.
