BitLocker is a built-in encryption tool in Windows, but it may not be available in all editions (e.g., Windows Home).

  1. Plug your USB memory device into your Windows computer.
  2. Search for “BitLocker” in the Windows search bar and select “Manage BitLocker” from the results.
  3. Find your USB memory device in the BitLocker window and click “Turn on BitLocker.”

  5. After setting up your unlock method, you’ll be asked to choose how you want to back up your recovery key. It’s crucial to save this recovery key in a secure place because you’ll need it to access your data if you forget your password or lose your smart card.
  6. BitLocker will then ask if you want to encrypt the whole drive or just the used space. Choose the one that suits your needs.
  7. Click “Start encrypting” to begin the encryption process. This may take some time, depending on the size of your USB drive.
  8. Once the encryption is complete, your USB memory device is protected with BitLocker. You’ll need to enter your password or use your smart card to unlock it whenever you plug it into a computer.

Step 3: Encrypt Your USB Drive

  1. Install and run the Folder Lock on your computer.
  2. The program’s main window will appear.
  3. Select “Encrypt USB drive” from this window.
  4. Insert your USB memory stick into the computer. The program will likely automatically detect your USB memory. However, if it doesn’t, click “Change” and manually select the USB memory you wish to encrypt or another hard disk space.

  2. Two .exe files will be present on the USB memory. The executable file allows access to the encrypted area, which is available only with the paid version of the program. However, this limitation shouldn’t be a significant concern for most users, as you can still view your files.
  3. You won’t be able to add files to the secure zone when using another computer. Only on your computer can you add new files to this encrypted domain.
  4. To add files to the safe area on your computer, open the program’s main window, click “Browse,” select the desired files from the window that opens, and copy them into the secure area.
