Note:If the "Encrypt contents to secure data" option is not selectable and grayed out or you do not see the option at all,you likely have a Home edition of Windows,which does not support this feature.It is also possible that the hard drive where the files are located is not formatted as NTFS,as this is a requirement for the encryption feature.
