Title Body

I'm trying to create an NTFS Junction. From the cmd line I can do this using the junction.exe tool from sysinternals . The output of a DIR cmd for a junction looks like this: Volume in drive C has no label. Volume Serial Number is C8BC-2EBD Directory of c:\users\cheeso\Documents 03/22/2009 09:45 PM <JUNCTION> My Music [\??\c:\users\cheeso\Music] 05/11/2007 05:42 PM <DIR> My Received Files 03/22/2009 09:46 PM <JUNCTION> my videos [\??\c:\users\cheeso\Videos] I read somewhere that Junctions are a subset of Symbolic Links. So I tried using CreateSymbolicLink to create a Junction. When I do this, I actually get a Symlink, not a junction. 09/09/2009 11:50 AM <SYMLINKD> newLink [.\] There is also CreateHardLink . The doc there says junctions (aka "Reparse Points") are a subset of hardlinks. but I can't seem to get this call to work. It completes but there is no hardlink or junction created. I'm using .NET/C# and the imports look like this: [Interop.DllImport("kernel32.dll", EntryPoint="CreateSymbolicLinkW", CharSet=Interop.CharSet.Unicode)] public static extern int CreateSymbolicLink(string lpSymlinkFileName, string lpTargetFileName, int dwFlags); [Interop.DllImport("kernel32.dll", EntryPoint="CreateHardLinkW", CharSet=Interop.CharSet.Unicode)] public static extern bool CreateHardLink(string lpFileName, string lpExistingFileName, IntPtr mustBeNull); What am I doing wrong? How can I create a Junction f
