..NET doesn't seem to have any managed support for accessing ADS so I would expect that Powershell lacks support as well. There are win32 api's that allow access... but you'd likely need a third party dll to use that from Powershell.

You could creatively use some command line commands that support ADS to *read* the contents of a stream. I'm sure variations of this could be adapted for writing... but nothing in native powershell.

Volume in drive C has no label.

PS C:\Downloads> $r = cmd /c "more < dotnetfx_v2.0.exe:Zone.Identifier:$DATA"

I'm using the library i mentioned in the former thread,

[void][System.Reflection.Assembly]::LoadFile("c:\powershell\ntfs.dll")

and I have the following in my typedata, I use for unblocking files, I still
have this on my "to blog" list

<Type>
<Name>System.IO.FileSystemInfo</Name>
<Members>
<ScriptMethod>
<Name>Block</Name>
<Script>
$FS = new NTFS.FileStreams($this.fullname)
$fs.add('Zone.Identifier')
$stream = $fs.Item('Zone.Identifier').open()

$sw = [System.IO.streamwriter]$stream
$Sw.writeline('[ZoneTransfer]')
$sw.writeline('ZoneID=4')
$sw.close()

$stream.close()
</Script>
</ScriptMethod>
<ScriptMethod>
<Name>UnBlock</Name>
<Script>
$FS = new NTFS.FileStreams($this.fullname)
$fs['Zone.Identifier'].delete()
</Script>
</ScriptMethod>
<ScriptMethod>
<Name>GetFileStreams</Name>
<Script>
$FS = new NTFS.FileStreams($this.fullname)
$fs
</Script>
</ScriptMethod>
