On NTFS a file can contain multiple data streams.  The syntax for
a secondary stream is <filename>:<streamname>.  However, not all
windows apps understand the syntax.

For example, try the following in a DOS or CMD box:

  copy <some-text-file>  example
  type <another-text-file>  > example:subfile
  more < example
  more < example:subfile

[The syntax is understood by CMD file redirection, but not by COPY.]
