C# Folder Lock

Last section we discuss about how to move a Folder and also how to rename a folder. Now we going to learn how to Lock the folder, we going to lock the folder WITHOUT any password. In this section we discuss about how to lock but we NOT discuss about how to unlock. So during you want try the program measure you create a new folder and delete it after lock.

Here we need to know what is CLSID. A CLSID is a globally unique identifier that identifies a COM class object. If your server or container allows linking to its embedded objects, you need to register a CLSID for each supported class of objects. msdn 

The CLSID we going to apply is window security {2559A1F2-21D7-11D4-BDAF-00C04F60B9F0}

This is very simple to lock the Folder without any password. We just move the file and rename the file New Folder to New Folder.{2559A1F2-21D7-11D4-BDAF-00C04F60B9F0}. Just add the .{2559A1F2-21D7-11D4-BDAF-00C04F60B9F0} at the back of the folder.

you also can try manually to add this CLSID code at the back of you folder name. The output will lock the folder.
