When selecting "Options" item from system menu the following dialog box will be displayed:

(click on a check box, input line or button to read the description of its purpose)

Secure Wipe:

If selected wipes the file(s) overwriting it (them) three times, using patterns 00,FF and F6.
Using an high value for the cache will reduce the efficacy of this option, since it is likely that the first two patterns are written to RAM and not to disk.   Anyway, even if you disable the program's cache, any caching program as Smartdrive(tm) will reduce safety as well.

If not selected owerwrite the file(s) only once.   This is enough to prevent file's recover using any utility program, tough.   If you choose this method disk caching doesn't affect at all the efficacy.

No beep:

If selected the program doesn't  play a WAV file when prompting for confirmation.

Cache size:

To improve speed the program may perform a disk-caching using a buffer up to 63 Kb.
Set this value to the minimum (1 Kb) if using secure wiping or to the highest  possible on your system if using normal wiping.


If selected performs a secure wipe.


If selected disables beep.


Determines cache size.


Saves current settings to options file and exit.


Wipe ONLY the file displayed in the dialog

Why use WipeForWin?

When you delete a file using the DEL command, only the first char of file name in the FAT is deleted:  file's contents are not overwritten until the operating system doesn't need that space, so it's possible using a disk utility to recover, entirely or partially, this data.

Most times this is a useful feature, but you may have some confidential data that you want to  wipe out.   For example, you may want to crypt a file and then wipe out the original.

WipeForWin overwrites entirely the data written to the file, in such  way that you can't recover it.
It may perform a normal wiping, overwriting the data only once, that is enough to prevent recover with any disk utility, or a secure wiping, that may be necessary if you think that a reading device more sensible than hard disk drive head may be used to recover data,
