How to Password Protect A File on Windows Computer

Gemma updated on Aug 05, 2021 to File Lock

Usually, people take care of their cell phones' data more than their computers' data. They use fingerprints and passcodes to prevent others from peeping into the chatting records and photos. However, the data on their computers are ignored involuntarily. Most users only set a Windows login password, which they think is sufficient to protect their computer and the files in it.

If you are one of these users we mentioned above, we would like to warn you that risks abound. The Windows login password is only basic-level protection, which can prevent others from logging into your computer, and this password is easy to crack. What you need to do is to employ more advanced measures on your important files and data. In this way, even if your computer is stolen or lost, and cracked by others, your files are still protected.

Method 1. How to Password Protect a File with Windows Built-in Feature

The very first method we'd like to introduce is the Windows built-in file encryption feature. This feature can encrypt both files and folders on your computer. Follow the steps below to see how you can do it.

Step 1. Find the file or folder you want to protect. Right-click it and choose Properties

Step 2. Under the General tab, click the Advanced button.

Click the Advanced button

Step 3. Tick the option of Encrypt contents to secure data, and then click OK.

Step 4. Continue to click the OK button in the Properties window. 

Step 5. Then you will see a Confirm Attribute Changes prompt, asking if you want to apply the change to this file only, or its parent folder. We recommend you encrypt the parent folder to be on the safe side.

Choose how you want to encrypt file

Step 6. After you have saved the changes, you will see a small yellow lock on the file icon.

Note: You should notice that this encryption is tied to your Windows account. Your files can be accessed through your account. If someone accesses your computer without authorization while you are logged in, encryption is actually useless. Only when other people log on to your computer with another account the file encryption works. 

Method 2. Password Protect a File with Third-Party Tool

If you have read the first method, you will know that regular Windows encryption has limitations. If you want a safer and stronger encryption method, you can try to use the third-party file lock software. One such tool is EaseUS LockMyFile, it is designed for users to lock and hide their important files and folders. Even with the same Windows account, you still need to enter a password if you want to access the files encrypted with this tool. 

Now you can download EaseUS LockMyFile from the button below, and follow the steps to see how to password protect a file with it.

Step 1. Enter "easeus" to launch EaseUS LockMyFile, register with a valid email and a license code.

Step 2. Click File Encryption under More Tools > Click Add Files or Add Folders.

Step 1. Open a document, click File > Info > Protect Document. Choose Encrypt with Password from the drop-down menu.
