Not to worry, found a fix. since the files being copied are be locked by a windows service, im just stopping and starting the service. However, if anyone does have any other sugestions, then please do let me know.

Does anyone know of a method that can be used that will do this? It doesnt strictly need to be .net as its a windows app that can run with admin privaliges if needed, so any workaround can be considered providing I can access it without human interaction from vb.net. Many thanks. Jamie.
