Ok, maybe i should explaine a bit further as it appears that there are a few different way to accomplish this. I have two arrays. RemoteFiles and LocalFiles. So I would like to do a compare against them to see if the files are the same. If they are remove them from the Remotefiles array. Note the RemoteFiles have a time stamp added to the file name as I am checking to see if they have been copied over before. Does this help?
