Hello

Does any of these products allow to see what files are openen by a process?
For example I have 4 pdf files openen on Aodbe Reader.
I've tried with Process Hacker and with Process Explorer and I can see the list of processes but I'm not able to view the files being used by them.
The Disk Activity task doesn't show that info either, I guess because I'm not writing.

Regards.
