I have seen many people in various sections and threads asking for ways of locking folders using the registry, etc. So, to hlp them, I have created an application in VB 6.0. What it does is add a CLSID extention to the specified folder so that Explorer recognises it as a system folder and opens that system folder. I am attatching it. Pls download, use and tell me how it is, as I havent finished the complete program as yet. Please also do give me suggestions.
