In nearly all cases, you can only access folders on a Windows computer once you're logged into your user account. But if multiple people use the same account on your computer — maybe you share it with your family — this leaves your folders open for snooping.

There's dozens of apps that let you encrypt your folders. But luckily, Windows offers its own built-in options for password protecting folders. Data Encryption Software

It's totally free and easy to password protect a folder in Windows. However, there are a few downsides.

The first is that you need to be running Windows 10 Pro — Home version won't let you. The second is that once you set the password, there's no way to recover it if you forget it.

Here's how to password protect a folder on your PC.

1. Open Windows Explorer and find the folder you want to password protect, and then right-click on it.

4. At the bottom of the Advanced Attributes menu that appears, check the box labeled "Encrypt contents to secure data."

6. Upon returning to the main window, click "Apply."

7. On the "Confirm Attribute Changes" window, choose between "Apply changes to this folder only" or "Apply changes to this folder, subfolders and files." 

9. A notification prompting you to back up your file encryption key will appear. Click "Backup now."

10. Insert a USB flash drive to your computer, and follow the on-screen instructions to create your encryption certificate and export to the USB drive.

Note: The final step is optional, but if you skip it, you run the risk of losing access to your encrypted files.
