While I was looking for information about streams in NTFS I found this little gem that I did not know, in Vista the dir command has be upgraded to be able to show streams as well.
If you do a Dir /R it will list all streams like this:
03-12-2007 11:16 23.993 ConsoleLib.ps1
03-12-2007 11:16 1.433 Get-ScriptParameters.ps1
01-02-2008 11:36 8.991 Init-TabExpansion.ps1
