How do I password protect my files and folders in Windows?

Tip: Before password protecting any document, you may want to create a backup of the non-password protected files and folder in case you forget the password in the future.

Not all versions of Windows include a method of password protecting your sensitive files and folders. If you are using Microsoft Windows 3.x, 95, or 98, you need to use a third-party program to password protect your files and folders in Windows.

Things to remember when encrypting or password protecting files and folders

Microsoft Windows Vista, 7, and 8 users

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

If you want 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 click Properties.
3. Click the Advanced button.
4. Check "Encrypt contents to secure data" option.
5. Click Apply and then Ok.

Note: If you cannot select the "Encrypt contents to secure data" option or do not see the option, you have a version of Windows that does not support this feature. It is also possible that the hard drive where the files are located is not formatted asNTFS, as this is a requirement for the encryption feature.

Microsoft Windows XP Professional users

The steps below for encrypting the files on Windows XP Professional applies to users who are using a computer that has different 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. Click the Advanced button.
4. Check "Encrypt contents to secure data" option.
5. Click Apply and then Ok.

The newest version of TweakUI also enables you to show the Encrypt option in the context menu. To do this, follow the steps below.

1. Open TweakUI.
2. In the TweakUI window, select Explorer
3. In the right side of the window under Settings, locate Show 'Encrypt' on context menu and check the box. This option should be below Prefix 'shortcut to' on new shortcuts and above Show 'View workgroup computers' in NetPlaces.

Microsoft Windows XP Home users

1. Select the file or folder you want to encrypt.
2. Right-click the file or folder and click Properties.
3. Click the Sharing tab.

For this option to work on Microsoft Windows XP Home edition, you must meet the below requirements.

1. The hard drive must be formatted in NTFS and not FAT32 File System.
2. The folder you are attempting to encrypt is your own personal folder. For example, if your name is bob, you must be encrypting a folder that is or that is contained within the below folder:
   
   C:\Documents and Settings\Bob\
   
   You cannot encrypt any folders outside of this folder. If you want to encrypt outside this folder, see the below other security solutions.

Other security solutions for protecting your files and folders in Windows

File and folders not frequently used - An easy way to password protect files is to create an archive of the files using a compression tool. When the archive is created, you can encrypt the contents by specifying a password.

Windows ME and Windows XP users - Windows ME and Windows XP come with their own compression utility. This utility can also be used to compress and password protect files.

Windows Vista and Windows 7 users - Windows Vista and Windows 7 also include a compression utility. However, password protection for the compressed files is not possible without the use of a third-party software program.

Tip: When a file is compressed, users can still view a listing of the files in the compressed file. If you want both your file names and the contents to be hidden, move all the files into a single folder and password protect that folder.

File and folders frequently used or accessed

If you need to password protect or encrypt data you frequently use, you need to install a third-party program that allows you to protect your files and folders. Below are some free and commercial solutions.

• 7-Zip - A free file and folder zipping utility, which also includes the ability to password protect zipped files and folders.

Things to remember when encrypting or password protecting files and folders

1. There is no such thing as a 100% protected file. There are numerous tools, utilities, and instructions for how to break encryption and passwords on files. However, the protection methods listed above will protect your files from the majority of 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 else to break the password, all the data in the file or folder will be lost. Thus, it is important to backup a copy of the non-password protected files or folders, just in case.
