An open file is a connection to shared resources, such as files or pipes. A pipe is an inter‑process communication mechanism that allows one process to communicate with another local or remote process.
DRA manages open files only on computers in the managed domain and managed subtree. Because open files are associated with a computer, you can manage open files while managing other resources for that computer. For example, you may want to close open files when you shut down a system or install a new device or service. You can also monitor which files users access most often, helping you better assess file security.
