If you have the Sysinternals SDelete.exe program on your system and would like to be able to right-click on a file or directory in Windows Explorer and have it securely delete that data, then I have just the shell extension for you. Download the SDelete.inf file, below, and securely delete away!
EDIT: I discovered that files and directories with the read-only attribute set on them will not be deleted, so make sure that you remove this attribute before running the SDelete command.
Please let me know if you have any problems with this.
Thanks!
Rob
