Step 1: Creating a Virtual Hard Disk

Type “diskmgmt.msc” in the Start menu and select Disk Management app from the search results.

In the Disk Management window, click on the “Action” menu, and then select “Create VHD” (Virtual Hard Disk).

Click the Browse button to choose a suitable location to store the virtual disk folder and give it a name (e.g., “Private_vault”).

Specify the amount of storage space you want to reserve for the virtual disk. The size will depend on the content you wish to protect (e.g., 2GB or more).

Optionally, select the VHDX format for the virtual hard disk, which provides better performance and reliability. Also, choose the “Dynamically expanding” option to allow the storage to grow as you add files. Click “OK” to create the virtual hard disk.

Initialize Disk

Right-click on the newly created virtual disk and select “Initialize Disk.”

Choose the “MBR (Master Boot Record)” option and click “OK.”

Next, right-click on the “Unallocated space” and select “New Simple Volume.”

On the Welcome screen, click Next. On the Specify Volume Size, use the default settings for the volume size.

Assign a drive letter to the virtual space or leave the default settings.

In the Format Partition table, change the Volume label to the virtual disk name (e.g. Private_vault). Leave the other settings and click Next.

On the “Completing the New Simple Volume Wizard“, click Finish.

Step 2: Enabling BitLocker Encryption

Type “Manage BitLocker” in the Start menu and BitLocker from the search result.

Under the “Fixed data drives” section, locate and select the virtual hard disk named “Private_vault.” Click on the “Turn on BitLocker” option to enable encryption for the virtual disk.

Choose the “Use a password to unlock the drive” option and create a strong password. Ensure you save the recovery key to a secure location or link it to your Microsoft account for recovery options.

Select the “Encrypt used disk space only” option for faster encryption.

Click “Start encryption” to initiate the BitLocker encryption process.

Step 3: Locking and Unlocking Protected Folders

To unlock folders protected with a password, open File Explorer and navigate to the location containing the “Private_vault.vhd” file.

Double-click the “Private_vault.vhd” file to mount it as a virtual drive. You will be prompted to enter the password you set during the BitLocker setup.

Upon entering the correct password, the virtual drive will be unlocked, allowing you to access your important files and folders.

To lock the folder again, simply eject the virtual drive (BitLocker encrypted drive) from File Explorer.
