You can add Encrypt or Decrypt option in Windows 7 right click context menu. Thus any file or folder can be Encrypted or Decrypted on single click. Here is how you can add the Encrypt or Decrypt option in right click context menu in Microsoft Windows 7.
Normally, in the Professional and Ultimate editions of Windows 7 and Vista, the encryption of files and folders using EFS encryption needs to be activated from the Properties of each file or folder to activate the encryption box.
Encryption is a method to enhance the security of a message or file by scrambling the contents so that only people with the appropriate encryption key to unscramble it can read them. For example, if you buy a product on a Web site, the information necessary for the transaction (such as your address, phone number and credit card number) are usually encrypted for security purposes. Use encryption when you want a high level of protection for your information.
The EFS (Encryption File System) is a Windows feature that lets you store information on your hard disk in an encrypted format. Encryption is the most enhanced protection provided by Windows to help you secure your information.
