File Wiper Utility
WF is a utility used to initialize a file to binary zeros before deleteing
it. This is handy for any sensitive files that you do not want to be "undeleted".
WF is a bound utility, ie. it will work under DOS or OS/2 operating systems.
Usage:
WF [-a] [-n] [-f] filespec
Where:
-a : turns off file wiping/deletion Acknowledgement message
-n : turns off permission to wipe file question and response;
No question/answer mode.
-f : turns on "Full" file mode of wiping. Normaly only the first
64K bytes of a file is set to zeroes as this is usually enough
to "eliminate" file recovery, however, on large files, this may
not be enough. The -f switch will clear the entire file. Of
course this switch is not necessary of files less than 64K and
is ignored on files less than 64K.
filespec : I decided this program is too dangerous to allow wildcard file
names, so if you want to have wildcards do this:
for %a in ( wildcard_filespec) do WF %a
Example:
WF -a -n test.dat
WF is a utility I wrote for my own use and I am willing to share it with
anyone, however I will accept NO liability of its use and hereby will
accept NO responsibility for its actions and results of its missuse.
