Handle is a utility that displays information about open handles for any process in the system. You can use it to see the programs that have a file open, or to see the object types and names of all the handles of a program. Handle can show you what files are open by which processes, and much more.

Handle is a small tool that allows you to search open file references, so if you do not specify any command-line parameters it will list the values of all the handles in the system that refer to open files and the names of the files. It also takes several parameters that modify this behavior.

usage: handle [[-a [-l]] [-u] | [-c <handle> [-y]] | [-s]] [-p <process>|<pid>] [name]
-a Dump all handle information.
-l Just show pagefile-backed section handles.
-c Closes the specified handle (interpreted as a hexadecimal number).
You must specify the process by its PID.
WARNING: Closing handles can cause application or system instability.
-y Don't prompt for close handle confirmation.
-s Print count of each type of handle open.
-u Show the owning user name when searching for handles.
-p Dump handles belonging to process (partial name accepted).
name Search for handles to objects with <name> (fragment accepted).
