Internet Zone is stored along a downloaded file

This is cool and fun stuff! At least for me :)
Stumbling on the article called
Description of how the Attachment Manager works in Windows XP Service Pack 2 when looking for other stuff, it caught my attention when I read this: When you save files to your hard disk from a program that uses the Attachment Manager, the Web content zone information for the file is also saved with the file. For example, if you save a compressed file (.zip) that is attached to an e-mail message to your hard disk, the Web content zone information is also saved when you save the compressed file. Later this The Web content zone information is saved together with the files only if the hard disk uses the NTFS file system, made me realize, that the information must be saved in an NTFS stream. I set on to reveal the information saved, so I started by using Streams from Sysinternals to list the steams -
C:\> streams TweakMCE.msi

NTFS Streams Enumerator v1.1

Systems Internals -

:Zone.Identifier:$DATA 26

Seeing the contents of a steam is not straightforward, but more can do it. Note the file name syntax -

C:\> more < zoneid="3">
Finally, the zone number can be translated to a name with reg -
C:\> reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\ ..

CurrentVersion\Internet Settings\Zones\3" ..
/v DisplayName



CurrentVersion\Internet Settings\Zones\3
DisplayName REG_SZ Internet

Also: a tipoff that a file has streams is a message you'll get while copying a file, say, to a CD (as I often do), "The file ... has additional information that will be lost upon copying. Do you want to copy this file"
