How to Encrypt a USB Flash Drive with BitLocker Windows 11

Encryption is one way to protect your data so that only certain people who have the key can access it.

If you have sensitive data, protecting that data by encrypting it will increase the security of that data. For example, if you have sensitive data stored on your computer and you do not encrypt it, then other people will easily retrieve your data by moving your hard drive to another computer as a second drive. However, if your drive is encrypted, when they try to open it will be asked to enter the encryption key. Without the key, they will not be able to find out the contents of the drive.
