メREAD MEモ for Obliterate, version 1.1

Obliterate without this documentation. Please do not modify this document.
REGISTERING OBLITERATE AND THE 7.0 PLUS UTILITIES
=================================================
Obliterate is not free. Sites using this software MUST register it by
sending a few dollars to the author. Or you can consider the following.
7.0 PLUS Utilities is a package of all (more than 25) System 7.0 utilities
I have written. You can get the disk with all of them NOW (not wait until
I decide to upload the next program) by sending $29.95 to me. This will
register you for all the software, will get you a disk of the software, and
an update to the PLUS Utilities when it rolls around. Itユs a pretty good
deal. You should register your software, anyway, so why not do it
like this? And itユs a lot cheaper this way.
See the documentation which should accompany this file for more information
on the 7.0 PLUS Utilities. A registration form should also accompany this file.
Please use it to register the software.
USING OBLITERATE
=================
・ If you use Obliterate, please please please send me a note. My addresses
(post and e-mail) are given below in メAbout the Authorモ. Also, read the
information in the above section on registration.
Why Does Obliterate Exist?
------------------------
・ Obliterate was designed because I hate having to select Empty Trash
all the time. I am not interested in any Extensions which
メautomaticallyモ empty the trash. I also wanted a facility to completely
remove a fileユs data from my disk and make it totally unrecoverable. Itユs
a scary idea, but it is sometimes necessary.
What Does Obliterate Do?
-----------------------
・ Obliterate, a drag-and-drop utilitiy (Drop Rob-Box), deletes all files and
folders with an optional shredding facility to make files totally
unrecoverable. All directories dragged into this drop box are scanned, so
you can throw in sets of files, folders or even disks, or any combination
of the three. You no longer have to go through the pain of selecting Empty
Trash all the time. This Drop Box requires Apple Events and thus System 7.0
or higher.
Using Obliterate
---------------
・ Drag sets of files, folders, or disks into the application, メDrop Box-
styleモ. Obliterate will scan folders and disks provided, and will
delete ALL files and ALL of the directories provided, no matter
what their depth. Drop Boxes require Apple Events, and thus System
7.0 or higher. Files on locked disks or open files will not be deleted
(for obvious reasons).
・ To cancel processing, just type a command-period. Cancelling in the
middle of a file might not prevent the current file from being
deleted. I suggest that you be ABSOLUTELY SURE that you can lose the
data.
・ Because of how the Finder handles aliases, when Obliterate is opened by
an alias, it actually gets a pointer to the resolved file (the Target or
Parent). That means that if you drop an alias directly into Obliterate,
the Parent will be obliterated (a bad thing, probably). The alert box says
the same before you are about to delete something. Keep this in mind!
Aliases within folders are not resolved, since I can handle them myself.
For example, say you have a folder, A, containing an alias, B, to your
System Folder. You make an alias folder A and call it C. But you
decide that you donユt want C, the alias, after all, so you throw it into
Obliterate. Obliterate receives the resolved reference to A (it knows
nothing about C). So it opens it up and finds a file (the alias file)
referencing your System Folder. That file, B, is deleted, and then the
folder A is deleted. So while your System Folder was safe, you lost
folder A, which contained an alias to the System Folder. The same thing
happens with files. In a nutshell: throw an alias into Obliterate and
delete the parent. Throw a directory containing an alias and the alias
is obliterated.
・ If you wish your documents to be totally unrecoverable (even through
file recovery utilities), you can optionally turn shredding on.
・ Double-click on the application to change the preferences and see the
About... box.
Preferences
-----------
・ The first time you try to modify a file using the program, the
preferences dialog will come up, just to make sure the correct
parameters have been set up. You can modify these if you wish. If
you don't want to see that window again, just say OK. You will have to
explicitly ask for for the Preferences window the next time you wish
to change anything.
・ To show the Preferences dialog in Drop Box mode, hold down the option
key while the program is launching.
・ The preferences are fairly self-explanatory. You can tell Obliterate
whether or not to display an alert to make sure you want the files to
be deleted. You can also tell it to shred files. Locked files can also be
obliterated. Remember that items on locked disks can never be
modified.
・ To bypass the alert, even if that preference is turned on, hold down the
shift key while the program is launching.
・ Shredding files replaces the fileユs contents with zeros. That means
that the data within the file is totally unrecoverable, even if you try
to use a file undeletion utility. This lets you keep private files private.
THE UPDATE
===========
Here is what has changed about Obliterate since version 1.0.
・ Shredding did not shred the resource fork (oops...) now it does.
・ Obliterate sometimes crashes on a Mac Plus/Classic. Now (hopefully)
it doesnユt.
・ Some other crashes have been fixed.
・ There are more warnings, especially about trashing aliases.
USING DROP BOXES
=================
Drop Boxes are applications which can take advantage of System 7ユs Apple
Events. To use them, just drag a file over the application icon just as you
would drag a file over a folder to move it into that directory. The Drop
Box is then opened and processing is done. The program then quits. You can
also throw in whole directories and disks. You donユt have to throw in just
one, either. Select a whole bunch of files, directories, or disks, or any
combination of the three, and dump them in. The Drop Box will scan for
files of the required type and modify them accordingly. All files in all
directories within those dropped in will be modified.
At least, that is how Drop Rob・Boxes work.
