File Monitor (formerly Filemon)

Keeping track of running applications and processes, as well as monitoring their particular activity, often requires a bit more than the functions available in Windows' Task Manager. File Monitor was developed with this particular purpose in mind, a lightweight program that can explore the way in which the OS works.

Straightforward GUI

The interface is very simple, quite plain actually, yet this is to be expected since it is a utility bent exclusively on practicality. The main window offers a generous space for viewing all the loaded processes and exploring their activity, as well as the resources in use.

View request results and configure timestamps

A great thing about File Monitor is that you can view if a certain application was successful or not in employing one component or another, and if a certain request was completed successfully or not. More so, there is a special column that displays supplemental information in some cases.
You can set File Monitor to automatically scroll the details presented in the main window, configure the time stamps to be in accordance with the system time and even show milliseconds. The latter options can be useful to better discern among many events of a single process, occurring in a very short period, for example.

Display network volumes

This utility is able to list all the available volumes and, from a dedicated menu, you can select only the ones you want to monitor. In addition to that, it is also possible to show mail slots and network volumes.

A last assessment

Perhaps the most important attribute of this software is that it is so easy to use that even novices can become accustomed to it and understand file system activity and working parameters in a rather short time.
The abundance of details and the filtering ability that allows users to select only the information they need to view, coupled with the fact that it is addressed to all user categories, makes File Monitor one of the best choices in its category.
