To remove CON or similar folders which cannot be delete by classical approach,all u need is WinRAR software.
run the winrar application, ADD the folder to archive which is to be deleted and set the option to Delete the current file after archive !

once done....the .rar file of da current folder will be created....! which can be deleted !!
