Slightly off topic but this the best NG I could find.

I want to create file streams using basic command line inputs, or any simple
utility.

For instance:

dir > aaa.txt

dir > aaa.txt:mystream

type aaa.txt

type aaa.txt:mystream

In theory this should work but my command window on WinXP/NTFS does not like
the syntax:

C:\stream>dir > aaa.txt (--->produces file of 333 bytes)

C:\stream>dir > aaa.txt:mystream (---> file size does not change,
suspicious)

C:\stream>type aaa.txt:mystream (--->shouldn't this work???)
The filename, directory name, or volume label syntax is incorrect.

C:\stream>type aaa.txt:$DATA (--->shouldn't this work???)
The filename, directory name, or volume label syntax is incorrect.

C:\stream>type aaa.txt::$DATA (--->shouldn't this work???)
The filename, directory name, or volume label syntax is incorrect.

C:\stream>type aaa::$DATA (--->expect to fail)
The filename, directory name, or volume label syntax is incorrect.

I am working as directed on
http://windowssdk.msdn.microsoft.com/library/default.asp?url=/library/en-us/FileIO/fs/file_streams.asp

What's going on? I have seen this work over someone else's shoulder.
