I need to know which files a Windows application reads/modifies/creates/deletes so I know a bit more about how it works.

Is there a good application for Windows, either free or affordable?

Thank you.

You can use the built-in Resource Monitor. Just go to the Disk tab and select the checkbox in front of the process you want to monitor.

For a more powerful solution, check out Process Monitor.

Thanks but I can't find Resource Monitor in XP. Is this a utility that's only available in Vista/7? – OverTheRainbow Apr 20 '12 at 15:05
Yes, that's only available in Vista and newer versions. For XP, use Process Monitor. Sorry, I should've asked you to specify the Windows version you were using. – Indrek Apr 20 '12 at 15:08
No problem. Processor Monitor looks like what I was looking for. I'll learn how to filter things further so it only shows files it writes/reads from the filesystem. – OverTheRainbow Apr 20 '12 at 15:13
I notice that PM displays a lot of duplicates, but doesn't seem to provide the option of hiding them. Instead of doctoring the log file in LibreOffice's Calc, is there a similar application that can only show unique operations? – OverTheRainbow Apr 22 '12 at 13:05
