Display alternate data streams of the file with normal command line tools

By Johan van Soest.
Published  :  2014-02-27.
Last updated  :  2017-05-02.
Show files containing alternate data streams with the command line command parameter:
dir /R
Example, the program Putty is downloaded from the internet and has an alternate data stream: 
D:\Download>dir /R
 Volume in drive D is Data
 Volume Serial Number is 5966-FF82

 Directory of D:\Download

01-02-2014  14:17    <DIR>          .
01-02-2014  14:17    <DIR>          ..
23-02-2014  10:04           495.616 putty.exe
                                 26 putty.exe:Zone.Identifier:$DATA
               1 File(s)        495.616 bytes
               2 Dir(s)  19.165.523.968 bytes free
The text contents of the alternate data stream can be shown using the command:
more < [FileName]:[DataStreamName]
Example: 
D:\Download>more < putty.exe:Zone.Identifier
[ZoneTransfer]
ZoneId=3
This example shows that the file is downloaded from the internet (Zone 3 is the Internet). Other ZoneTransfer ZoneId's are:
  • INTRANET = 1
  • TRUSTED = 2
  • INTERNET = 3
  • UNTRUSTED = 4
Because of the ZoneId 3, the downloaded program upon starting shows the security warning:
While files from the Internet can be useful, this file can potentially harm your computer. Only run Software from publishers you trust.
