X Utilities
The included utilities are potentially hazardous. No, they do
not contain a virus, trojan horse, or any other patently malicious
code in them. Rather, these utilities are very powerful at removing
files from your disk (hard drive and/or floppy). With this level
power comes the opportunity for YOU the user to make a mistake of
larger consequence. Below are description of what each utility
does.
XDEL - works much like xcopy, except in reverse. XDEL will erase
files just like del or erase does at the DOS command line.
XDEL has some options that neither del nor erase have.
These options are:
pause - XDEL can pause before deleting to ask if you
actually want to delete that file.
erase - XDEL can erase empty subdirectories.
search - XDEL will search subdirectories for matching files
and delete them as well if you want.
date - XDEL will only erase files modified before a date
that you give it. Used to get rid of old files.
hidden - XDEL will erase any hidden files as well as unhidden
files it finds.
read only - XDEL will erase any read only files it finds.
list - XDEL lists all files it deletes and all
subdirectories that it removes. You can turn this
off (quiet) if you want or redirect it to your printer.
KILL - truely erases a file from the disk by writing over the old
data with alternating bytes equal to 85 and 170. Why does
it use those two numbers? 85 in binary is '01010101' and
170 in binary is '10101010'. They are alternating ones and
zeros. Using KILL will therefore completely remove a file
beyond any disk recovery program's capability to retrieve
that data (the type of erasing that Ollie North needed).
So, if you are highly recommended to backup your files
before running KILL.
XKILL - a combination of XDEL and KILL. XKILL will erase files by
writing alternating 1's and 0's over existing files that are
to be killed, then delete them. XKILL has the same options
that XDEl has, and uses the same siwtches to select those
options.
You can use XDEL in place of del or erase if you like as, it
works the same way. Subdirectories are only searched and/or
erased if you tell XDEL to do so.

OTHER SHAREWARE SOFTWARE
Look for LITLMENU.ZIP (or LTLM_xxx.ZIP), a menu program for DOS
compatible computers. LitlMenu is extremely fast, uses both keyboard
and mouse input, has a screen saver, allows you to shell to DOS, and
works in color or mono. MainMenu, the registered version, uses less
than 1k RAM! NetMenu, the registered version for local area networks
uses only 1.5K RAM. Available soon with all three versions is
MicroShell, a small DOS Shell program. MicroShell will allow you to
copy, format, check disks and directories, and more without having
to use the DOS command line.
