FileSystemWatcher.ps1

#By BigTeddy 05 September 2011

#This script uses the .NET FileSystemWatcher class to monitor file events in folder(s).
#The advantage of this method over using WMI eventing is that this can monitor sub-folders.
#The -Action parameter can contain any valid Powershell commands.  I have just included two for example.
#The script can be set to a wildcard filter, and IncludeSubdirectories can be changed to $true.
#You need not subscribe to all three types of event.  All three are shown for example.
# Version 1.1
