How to get file handle by path?

Question

Sometimes during debugging I need to get handle value for known object (file or dll) opened by debugee. It can help to find who holds this handle.

How can I achieve that?

Answer 1

There is Sysinternals's utilities named Handle and Process Explorer.

Handle has command line interface and should be used like this:

handle [-p <pid>] <file path>

To get handle value in Process Explorer:

1. Go to main menu View -> Select Columns...
2. Switch to Handle tab
3. Check Handle Value
4. Open Handle pane for desired process
