I'm trying to add the ability to use sdelete within the context menu to erase files and/or folders securely. I know about the alternatives, but I admittedly like command line applications. I might need a little help in doing so because nothing I have tried as worked. I have created the following registry entry, which then points to the below bat. sdelete.bat I cannot figure out why this does not work. When I execute the script I'm told that sdelete is using an invalid argument switch. I can only guess that it is referring to the "%1". But I believe that to be correct. Any ideas?
