windows - Identify process using a file

Question

I have been trying to figure out how to programmatically identify the process that has a lock on a particular file. I've searched through the Win32 API and WMI, but so far I can't find anything. I know it's possible - Sysinternals is able to list every resource accessed/locked by every process on the system.

Can anyone drop me a hint?

Answer 1

You can use handle.exe from Sysinternals.

Something like:

> handle /accepteula C:pathodirectory
...
program.exe           pid: 1234   type: File           2E4: C:pathodirectory
...
