BCWipe software enables you to confidently erase files that can never be recovered by an intruder. BCWipe embeds itself in Windows and can be activated from the Explorer FILE Menu OR from the context (right click) menu OR from a command-line prompt. BCWipe v.3 is a powerful set of utilities which complies with options to invoke either the US Department of Defence (DoD) standard or the Peter Gutmann wiping scheme. You can also create and use your own customized wiping scheme to wipe sensitive information from storage devices installed on your computer.
