Why Password Protect a Folder

You may need to password protect a folder under the following circumstances:

  • Multiple people use the same account on a computer. Partitions, folders, and files are accessible to all.
  • There are confidential or private folders on the computer that cannot be disclosed and need to be protected.
  • If you share a computer with others, it's efficient to prevent folders from being modified or deleted by password protection.
  • Protect a folder with a password for additional file security. In the case that your computer gets hacked or even stolen, it’s not easy for someone else to access your important folder.

If you have some folders that contain sensitive and crucial information, such as financial or health records on your computer, it’s a good idea to use a password to lock the folder. Protecting a folder with a password means that you need to enter a password to view the files in the folder.

This post focuses on how to password protect a folder on Windows 10 and Mac. Learn how easy it is to secure your folders with password protection and encryption.

How to Password Protect a Folder in Windows 10 via Properties

Windows 10 offers a free file encryption option with the password. Once you've created a new folder that needs to be encrypted, here's how to password protect it. 

Notes before start:  


1. If you forget the password for a folder, you can't recover it, so be sure to write it down somewhere.

2. Before setting up a password-protected folder, you should copy the files in the folder to an external hard drive or another place so that you can access them even if you lose your password.

3. You can only password protect folders in Windows 10 Pro. It's not available in Windows 10 Home. 

Step 1. Press Win +E keys to open Windows File Explorer and find the folder you want to password-protect.

Step 4. Go back to the main window, click "Apply".

Step 5. A notification window will then pop up prompting you to back up your file encryption key. Click "Backup now" and back up the encryption key to a removable media as recommended.

This step is optional, you can skip it. But you will run the risk of losing access to your encrypted files if you forget the password.

Windows password encryption is tied to your current Windows account. The folders will be dynamically decrypted by the operating system when you log in with your account. If someone logs in through another account, they will not be able to access files that are encrypted under your username.

However, there is a case where encryption is actually useless if someone has unauthorized access to your computer while it is logged in. But the Windows encryption can only do so much.

To solve this problem, we will introduce you to the following powerful file lock software.
