    Ricardo: Hi,
    Ricardo:
    Ricardo: I am just trying to get some info on the best method available for having
    Ricardo: files encrypted on a system. This is a laptop that is going to be used
    Ricardo: outside our physical environment and I would like to make sure that info is
    Ricardo: not accessed in case of the laptop going missing, etc...
    Ricardo:
    Ricardo: I understand that the Windows EFS implementation had some issues on win2k,
    Ricardo: and that the XP implementation is slightly better. Any comments on that?
    Ricardo:
    Ricardo: Any solutions for win98?
    Ricardo:
    Ricardo: Thanks in advance.

    I highly recommend and use PGPdisk (v. 6.0.2i).

    Assuming the laptop was stolen and the account (that uses EFS) is cracked,
    EFS will not help you as the data is still readable.

    At least with PGPdisk, you must enter a password to decrypt the file which
    then mounts itself as a drive letter.

    Then again, since you asked about Win98, EFS is not a part of that OS.
    EFS is only availiable on NTFS 5.0 and higher (ie: Windows 2000 and
    higher)
