information   Information
Encrypting folders and files on your local internal hard drives is a way to protect them from unwanted access. Encrypting File System (EFS) is a feature of Windows that allows you to store information on your hard disk in an encrypted format. Encryption is the strongest protection that Windows provides to help you keep your information secure.

This feature is only available in the Vista Business, Ultimate, Enterprise, Windows 7 Professional, Ultimate, Enterprise, and Windows 8 Pro and Enterpise editions.

Note   Note
Encryption is based on your username. So if you encrypt a file or folder and you try to open the file, the file is automatically decrypted. If you try to open the encrypted file or folder while logged in with another username, then the file or folder remains encrypted and will not open. There is no password to open the files, only your username credentials are used as password.

This will prevent other user accounts from being able to open the encrypted file or folder. Even another Administrator account. If you create a shortcut from the encrypted file, it will not be encrypted by default. The shortcut will still not be able to be read by any other user account or computer since it is linked to a encrypted file.
warning   Warning
If you add a encrypted file to a compressed (zipped) folder, the file will be unencrypted (decrypted) when extracted from the ZIP file. This might result in unintentional disclosure of personal or sensitive information.
Tip   Tip
If you lost your EFS certificate or did not make a backup (step 10 below), then you can use the 30 day free trial program Advanced EFS Data Recovery to decrypt the files.

EXAMPLE: Folder Not Encrypted (Decrypted) and Folder Encrypted
NOTE:
Notice that the text is now green to show it is encrypted.

2. Under the General tab, click on the Advanced button. (See screenshot below)​

3. To Encrypt a File or Folder
A) Check the Encrypt contents to secure data box and click on OK. (See screenshot below step 4)​
NOTE: You will only be able to choose to Encrypt or Compress contents, not both at the same time. If Encrypt contents to secure data is grayed out, then see this link to enable it:How to Disable or Enable Encryption in Vista.​
B) Go to step 5.​

5. Click on OK. (See screenshot below step 2)​
6. For a Folder

C) Go to step 9.​

7. For a File
A) Select (dot) if you want to Encrypt the file only, or Encrypt the file and it's parent folder. (See screenshot below)​

B) Leave the Always encrypt only the file box unchecked to always have these options.​
C) Click on OK.​
NOTE: It may take a second to encrypt or decrypt the file and close Properties.
