    1/ Enhance the /W (wipe) option of the DEL and MOVE commands by adding an
    optional count field, e.g. /W100. If the count field is used, it specifies
    the number of times the file is to be wiped, where "wiped" means each bit is
    overwritten twice, once with a 1 and once with a 0.

    2/ Add the enhanced /W option to the RECYCLE command to permit wiping files
    which had already been moved to the recycle bin (typically by programs other
    than TCC).

    3/ Add an option to MOVE to move the original file to the recycle bin of the
    source drive when the file is moved to another drive. Using /W would need to
    override this new option, as is done in DEL.

    If the /W is to be enhanced, I'd suggest that using established DoD or NIST
    or NSA or other (international) governmental agencies' recommended methods.

    At least one NIST document I read suggested that overwriting once with
    modern media was sufficient.

    I would prefer secure deletion using Gutmann.
