JSI Tip 1658. How can I display a list of processes that have files open?

Download HandleEx from www.sysinternals.com.

Ever wondered which program has a particular file or directory open? Now you can find out. HandleEx is a GUI/device driver combination that together show you information about which handles and DLLs processes have opened or loaded. Its display consists of two sub-windows. The top always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that HandleEx is in: if it is in handle mode you’ll see the handles that the process selected in the top window has opened; if it is in DLL mode you’ll see the DLLs that the process has loaded. HandleEx also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded.
