Does Anyone Know The Cipher Strength Of The NTFS EFS System?

I'm looking into certain 3rd party products designed to secure sensitive
data using 400+ ciphers, but without knowing what the NTFS Encrypted File
System supports natively, it will be difficult to really compare the
benefits of using such an app against dumping the data into Office files and
saving them to a secured area in an encrypted folder on an NTFS volume.
I've got a couple good arguments, but the cipher level is really the most
important.

Thanks,
Bob

see this MSDN description of EFS. This was written for Win2k, but AFAIK, the
"level of encryption" should be the same or similar to EFS implemented in
WinXP. http://tinyurl.com/owe77
 
I am not certain of the cipher level, but I do know that I have never heard
of anyone recovering their own files when they have been foolish enough to
not have backed up the encryption key. When they reinstall their O/S, their
files are unusable - forever.
