Honestly what are you looking for is an amzing tool by PernixData. This is technically a competing tool to EMC. However we are both a Pernix and EMC partner. We always load Pernix onto a Virtualized enviornment and use it to discover the current IO characteristics and working set size. Check out this presentation form VFD5. Pretty spot on with what you are asking for around Working set size. If you are asking to determine the working set size for a Virtualized workload. PernixData FVP Update and Futures - YouTube

Hi.
Honestly, I am not 100% sure what you are looking for... but I will take a chance at providing you some useful tools to determine "open" files.
In Linux the "lsof" command has the ability to tell you what files are open: 15 Linux lsof Command Examples (Identify Open Files)
With Windows there are a couple of challenges but in general "netstat -b" will work for the same goal of seeing open files. "tcpview" is another program that might be worth a look.
Best Wishes
