Encrypting a File Folder

Windows includes a feature that allows you to encrypt information stored on the hard drive. This security feature means that anything in the folder is "scrambled" in such a way that only you can access it. If someone other than you logs into your system (using a different user account), they won't be able to access the information in the folder.

The encryption feature is technically referred to as EFS, or Encrypting File System. It has been available since Windows 2000, but is not fully supported in all versions of Windows 7 and Windows 8. (It is only fully implemented in Windows 7 Professional, Enterprise, and Ultimate editions. In Windows 8 it is only fully implemented in the Pro and Enterprise editions.)

To encrypt a file folder, follow these steps:

1. Use Windows Explorer to display the file folder you want to encrypt. (Display the actual file folder, not the file folder's contents.)
2. Right-click the file folder and choose Properties from the resulting Context menu. Windows displays the Properties dialog box for the folder.
3. On the General tab, click the Advanced button. Windows displays the Advanced Attributes dialog box. (See Figure 1.)

4. Select the Encrypt Contents to Secure Data check box.
5. Click OK to close the Advanced Attributes dialog box.
6. Click OK to close the Properties dialog box for the folder.

The change is immediately applied and the folder contents are encrypted. You won't notice any difference in how you use the folder or its contents. The real difference is when others, using a different Windows user account, try to access the information in the folder. They will not be able to use it.
