Setting Extended Properties with PowerShell

We’ve been looking at working with extended file properties with PowerShell using the Shell.Application COM object.

$shellApp = New-Object -ComObject 'Shell.Application'
$path = 'C:\work'
$shellFolder = $shellApp.NameSpace($Path)
$file = $shellFolder.Items() | where { $_.name -eq 'PHI_4928.jpg' }

Once you know the attributes you want, you can create custom output.

[PSCustomObject]@{
    Name = $shellFolder.GetDetailsOf($file, 0)
    Size = $shellFolder.GetDetailsOf($file, 1)
    Dimensions =$shellFolder.GetDetailsOf($file, 31)
    BitDepth = $shellFolder.GetDetailsOf($file, 174)
    Camera = $shellFolder.GetDetailsOf($file, 30)
}
