I deleted the entire subfolders "open" and "explore" from the folder HKEY_CLASSES_ROOT/Folder/shell via regedit! After deleting a one line entry which worked and took away the option of scanning a folder with NAV2005, deleting the entire folders which looked so innocent and small has completely screwed things up! I can't open/explore folders of course, now I have to use search. Anyone know if I can reclaim the entries?? I have Advanced Registry Tracer, can this save me??
