How it works

windows-system-icon uses Powershell in the background to extract the associated file icons.

Here is the powershell script that gets executed in the background:

Add-Type -AssemblyName System.Drawing
 
$filePath = "<input-file-path>";
$fileExists = Test-Path -Path $filePath;
 
if ($fileExists -and $filePath.EndsWith(".lnk")) {
    Try {
        $sh = New-Object -ComObject WScript.Shell;
        $filePath = $sh.CreateShortcut($filePath).TargetPath;
    }
    Catch {
        <# do nothing #>
    }
}
 
if ($fileExists) {
    $icon = [System.Drawing.Icon]::ExtractAssociatedIcon("<input-file-path>");
    $bitmap = $icon.ToBitmap().save("<output-file-path>", [System.Drawing.Imaging.ImageFormat]::<output-format>); 
}
