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
You can use handle.exe from Sysinternals.
Something like:
> handle /accepteula C:\path\to\directory
...
program.exe pid: 1234 type: File 2E4: C:\path\to\directory
...
