Show open files on SMB shares

#requires -Version 3.0
<#
.SYNOPSIS
Shows files that clients have open on SMB shares.

.DESCRIPTION
This script runs Get-SmbOpenFile, which retrieves basic information about the files that are open on behalf of the clients of the Server Message Block (SMB) server.

.NOTES
The required SMBShare module is only available on Windows 8/2012 and later, so this script will not run on older Windows versions.
Based on an idea by Dennis Geerlings
