How to password protect files and folders in Windows

Because most versions of Windows do not include a method of password protecting your files and folders, this page provides steps for encrypting files and folders instead. To password protect your files and folders in Windows, you must use a third-party program.

Microsoft Windows Vista, 7, 8, and 10 users

Unfortunately, Windows Vista, Windows 7, Windows 8, and Windows 10 do not provide any features for password protecting files or folders. You need to use a third-party program to accomplish this.

To encrypt a file or folder, this can be done by following these steps:

1. Select the file or folder you want to encrypt.
2. Right-click the file or folder and select Properties.
3. On the General tab, click the Advanced button.
4. Check the box for the "Encrypt contents to secure data" option, then click OK on both windows.

Microsoft Windows XP Professional users

The steps below for encrypting the files on Windows XP Professional apply to users who are using a computer with two or more accounts. If you are using a single account, see the other security solutions section.

1. Select the file or folder you want to encrypt.
2. Right-click the file or folder, and click Properties.
3. On the General tab, click the Advanced button.
4. Check the box for the Encrypt contents to secure data option.

   C:\Documents and Settings\Bob\
   
   You cannot encrypt any folders outside of this folder. To encrypt folders outside of this folder, see the other security solutions section below.

Things to remember when encrypting or password protecting files and folders

1. There is no such thing as a 100% protected file. There are many tools, utilities, and instructions for how to break encryption and passwords on files. However, the protection methods listed above will protect your files from most users who may encounter them. If you are working with really sensitive data, we suggest a commercial product for protecting your files and data.
2. Even though a file or folder may be password protected, it still can be deleted (unless the program supports the ability to protect files from being deleted). Always remember to backup all your files, even those protected by passwords.
3. If you forget the password, unless you're willing to spend the time attempting to break it or pay someone, all the protected data is lost. Thus, it's important to back up a copy of the non-password protected files or folders, just in case.
