-
- When your ST deletes a file from a disk only the directory entry is
- removed and all of your data remains intact on the disk. This allows you
- and other people to un-delete your erased files and view your precious
- data. If you want to protect your data from prying eyes, use File
- Killer™.
-
- What is File Killer™..?
-
- File Killer™ is a small utility that can be placed in the AUTO folder of
- your boot disk that allows you to delete files forever.
-
- How does File Killer™ work..?
-
- File Killer™ erases files by overwriting them with completely random
- data before deleting the file in the normal way. Even if you did try to
- un-delete the removed file, all you would get is a file full of garbage.
- File Killer™ uses a well proven random number generator known as
- Linear Congruential Method which was developed by D. Lehmer in 1951 and
- documented in a book called: 'Algorithms in C' by Robert Sedgewick.
-
- To completely erase a file, you must hold down the Alternate key when
- you delete the file. Your ST will beep once and the screen will flash
- while the file is being deleted.
-
- WARNING.. WHEN YOU HAVE ERASED A FILE USING FILE KILLER™, YOU WILL NOT
- BE ABLE TO RECOVER IT, SO BE VERY CAREFUL.
-
- File Killer™ was inspired by a brilliant program from DO NOT STAMP
- SOFTWARE called Shredr Plus. Shredr allows you to permanently delete
- files also, but has many extra options for those who take security
- seriously. If you like the idea of File Killer™ then you'll love Shredr
- Plus.

- Compatibility / Technical details:
-
- File Killer™ is a small program that uses a tiny amount of RAM, and detects
- file deletions by re-directing the Gemdos (TRAP #1) vector. It has an
- XBRA ID of 'FKIL', don't worry if your favourite virus checker complains
- about an invalid vector as some viruses link into the same place. File
- Killer™ should work on all versions of the ST, but will not work on the TT
- or ST's that are fitted with non 68000 accelerator boards, like Gadget's
- SST or TinyTurbo 030. When I can get my hands on a TT (or a 63030
- board), I will produce a version that will function on this hardware.

-
- File Killer™ is distributed as shareware, for details of how to
