Ask HN: What is the best way to see what files are being read in Windows? I am looking at migrating a Windows server (Windows Server 2012 R2 Standard) and I am wondering if there is some way to learn what files are being read. I know the operating system keeps this metadata but I have also learned that this metadata is unreliable. Is there a third party tool or some kind of powershell script I can use to track this data? |

Here's a good, basic video tutorial from Scott Hanselman, explainer extraordinaire:

for reference, your goal is to detect operations on files and report file, i.e. build a process monitor that you can trust and have granular control.

the system calls have consequences and results that you may use for your way of detecting file status. very oversimple example is just try to do something to a file, and look at results. if the file is unused, you will get results; if the file is busy, you will get some sort of exception or system flag.
