Open command prompt. change to the directory in which u want to make folder. type mkdir .\con\\ Or Md .\con\\
You can choose folder name from the name given below CON LPT1 LPT2 LPT3 LPT4 LPT5 LPT6 LPT7 LPT8 LPT9 AUX ----------------------- Logic behind this is : IN Windows above names are researved words and you cann't create folder or file with above name. Once you will create the folder nobody will be able to delete it in normal way. I have tested it with XP 2000 and 2003. Windows 98 is currently not available to me for testing. If you can test it on Windows 98 then please do it and let me know the result. I expect it to work.
