# 9 PSFileThe PStools set of utilities are definitely popular and extremely useful, but one that I recently discovered is PSFile. This utility shows files on a system that are open by remote systems by default, but can be passed parameters to return information about remote systems as well. This tool is a good way to check for open files on file servers when users might report read only issues or have problems getting files open properly.
