Never heard of these "NTFS streams" before.  Wow!  Unbelievable!  Ugh!  A
new way to hide data, even better than dot files.

$ echo c >foo
$ echo abcde >foo:1
$ ls -l foo*
-rw-r--r--    1 jrw      JRW             2 Jun 27 12:21 foo   <= note: only
2 bytes
$ cat foo:1
abcde
$ cp foo bar
$ cat bar
c
$ cat bar:1
cat: bar:1: No such file or directory

(Using Windows Explorer to copy foo to bar does also copy all streams, so
that bar:1 can be read)
