Hello Dave,
           I tried with efsinfo from Microsoft TechNet Article ID 243026
‘Using Efsinfo.exe to determine information about encrypted files’. But this
Efsinfo.exe file is not available on my standalone PC. It is clearly written
in this article that ‘Stand-alone Windows 2000 workstations and servers do
not display the recovery agent information. The default recovery agent for
all stand-alone computers is the local Administrator account.’

        I couldn’t solve this problem using google help.

        No files in this folder are encrypted or read only. Only the folder is
secured. This is applicable to all types of files not just MSoffice files. In
the above trial if we move some files in user mode who has secured the
folder, other users even administrator can’t see the contents of these files.
        This appears to be a good feature of folder protection. But how to make use
of this?
