- 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’s a pretty good
- deal. You should register your software, anyway, so why not do it
- like this? And it’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 “About the Author”. 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
- “automatically” empty the trash. I also wanted a facility to completely
- remove a file’s data from my disk and make it totally unrecoverable. It’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, “Drop Box-
- style”. 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’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’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’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’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’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.
