Class KShred

public class KShred extends QObject

Erase a file in a way that makes recovery impossible -- well, no guarentee of that, but at least as difficult as reasonably possible. For this, KShred write several times over the existing file, using different patterns, before deleting it. See KShredSignals for signals emitted by KShred
