Encrypt or Decrypt Files in Vista

To Encrypt or Decrypt files in Windows Vista simply right-click on the item and select Properties. Next, under the General tab click on the Advanced button. Now, either check or un-check Encrypt contents to secure data and hit OK. Finally, click Apply (If you are encrypting you will be prompted whether you want to encrypt just that file or also the parent folder). Thats it. Now your file is either encrypted or decrypted.
