I am using Norton Utilities version 16.0.1.4 on Windows 7 Home, and on Windows 8.1 Pro; on both OS's when using 'Shred Files' its stated ability of "drag and drop specific files and folders directly into the list. . ." does not work. I must use the optional (and much more indirect) method of using "Click Add to browse your commputer."
Perhaps this will be fixed in an upcoming update, or the next refresh of Norton Utilities?
regards,
Laurence
