Determine file activity of an app with ProcessActivityView

processactivityview_icon I am quite fond of troubleshooting tools and usually have a lot of opportunities to use those. ProcessActivityView is sister utility to OpenedFilesView and unlike latter (or overpowered Process Monitor) is made to trace file activity of single process.

What it does

On launch app prompts to choose currently running process and starts to monitor its file activity.

processactivityview_interface

Interface is typical for Nirsoft software – minimalistic and with numerous columns that can be toggled and used for sorting.

App adds index by order of files accessed so is very good for detecting specific patterns of files used together.

Resource usage

Narrow focus allows software to be extremely efficient. Processor overhead is very low and prolonged usage doesn’t consume excessive memory.

Overall

Simple, efficient, works without installation and perfect for anything from tracing those elusive profile-specific application settings to virus activity.

    Can't wait to get home and try this one out. I had a call over the weekend (perhaps it was 2 weekends ago, I can't remember), where a friend had the xp-police-av virus. Locked the taskbar and ran under a different name as well. Took me a few days but I managed to track it down and delete everything relating to it in the end. This would have made the whole process much easier as I knew the process name, I just didn't know what it was working with. I worked with a few of the Nirsoft networking tools, but I never really spent any time browsing around the website. I never realized how many different apps were available. Thanks for this post!

    @Angelo I can definitely relate to the "I wish I had this app" feeling. :) While Sysinternals has some awesome general purpose troubleshooting utilities Nirsoft excels at simple single-function ones. Site definitely worth exploring, which I often do.

    I love tools by Nirsoft, their driver viewer is excellent as is their usb device viewer. Not seen this one before though I'll give it a go,

    @Jonny Yeah, need to do a post on USB one. Didn't actually use driver one, soooo many of those utils. :) Need to check it out.
