The easiest method is to encrypt the file using the native file encryption feature.

How to Lock a File in Windows 10

Locking a file in Windows 10 is a straightforward process that involves using either built-in encryption features or third-party software for enhanced security.

Step 1: Right-click the file

Right-click on the file that you want to lock.

By right-clicking, a context menu will open up with various options to modify or interact with the file. This is your gateway to accessing additional file properties and settings.

Step 2: Select ‘Properties’

Click on ‘Properties’ from the drop-down menu that appears.

This action will open a new window displaying the file’s attributes, including its size, location, and other file-specific information.

Step 3: Go to the ‘General’ tab

Navigate to the ‘General’ tab in the Properties window.

The ‘General’ tab provides a general overview of the file, but more importantly, it offers a button for advanced settings.

Step 4: Click on ‘Advanced’

In the ‘General’ tab, click the ‘Advanced’ button.

This will open another window where you can find more options for file attributes, including encryption.

Step 5: Check ‘Encrypt contents to secure data’

This step adds a layer of security by encrypting the file, making it accessible only through your user account.

Step 6: Confirm changes

Apply the changes by following the prompts, and click ‘OK.’

Windows will ask you to confirm your choice; this is the final step in encrypting your file.

Once you’ve completed these steps, the file will be encrypted. Only users with the correct credentials will be able to access it. Windows will also create an encryption key, making it important to back up this key for future access.
