Enumerate file properties in PowerShell

Sounds like you are looking for extended file attributes. These are not stored in System.IO.FileInfo.

One way is to use the Shell.Application COM object. Here is some example code:

Say you had a video file: C:\video.wmv

$path = 'C:\video.wmv'
$shell = New-Object -COMObject Shell.Application
$folder = Split-Path $path
$file = Split-Path $path -Leaf
$shellfolder = $shell.Namespace($folder)
$shellfile = $shellfolder.ParseName($file)

You'll need to know what the ID of the extended attribute is. This will show you all of the ID's:

0..287 | Foreach-Object { '{0} = {1}' -f $_, $shellfolder.GetDetailsOf($null, $_) }

Once you find the one you want you can access it like this:

$shellfolder.GetDetailsOf($shellfile, 216)
