Do you have the experience that your system settings are changed unwillingly? Some unwanted changes are dangerous for us, but when we find them the losing has come into being. Does not there has an effective and safe way to avoid this happening again? Certainly not! Do not worry about it any longer! Here I commend you a powerful and esay to use utility that can monitor system activity for us. That is Filemon which was published by Sysinternals. With Filemon my operating system is keeping safe and steady until today. Below I will introduce this usful application to you amply.

Filemon can monitor and display file system activity on a system in real-time. Its advanced capabilities make it a powerful tool for exploring the way Windows works, seeing how applications use the files and DLLs, or tracking down problems in system or application file configurations. Filemon time stamping feature will show us precisely when every open, read, write or delete, happens, and its status column tells us the outcome. Filemon begins monitoring when we start it, and its output window can be saved to a file for off-line viewing. It has full search capability, and if we find that we are getting information overload, simply set up one or more filters. Filemon has been replaced by Process Monitor on versions of Windows starting with Windows 2000 SP4, Windows XP SP2, Windows Server 2003 SP1, and Windows Vista. Filemon remain for legacy operating system support, including Windows 9x. FileMon works on NT 4.0, Windows 2000, Windows XP, Windows XP and Windows Server 2003 64-bit Edition, Windows 2003 Server, Windows 95, Windows 98 and Windows ME. Following are some main features and benefits of this system activity monitor, including: Filtering ¨C we can use the Filter dialog, which is accessed with a toolbar button or the Edit|Filter/Highlight menu selection, to select what data will be shown in the list view. Use the highlight filter specify output that we want to have highlighted in the list view output. Select highlighting colors with Edit|Highlight Colors. Additional filter options select or deselect read, write or open operations. In many troubleshooting scenarios only open operations are of interest, for example. Selecting Volumes (Windows NT/2K/XP/2K3) - The Volumes menu can be used to select and deselect monitored volumes. Select the Network menu item to monitor accesses to any network resources, including remote shares and UNC path name accesses to remote volumes. Limiting Output - The History Depth dialog, accessed via toolbar button or the Edit|History menu item, allows us to specify the maximum number of lines that will be remembered in the output window. A depth of 0 is used to signify no limit. Searching the Output ¨C We can search the output window for strings using the Find menu item (or the find toolbar button). We can repeat the search in the forward direction with the F3 key and in reverse with Shift+F3. To start a search at a particular line in the output, select the desired line by clicking on the far left column (the index number). If no line is selected a new search starts at the first entry in searching down, and at the last entry for searching up. Options - FileMon can either timestamp events or show their duration. The Options menu and the clock toolbar button let us toggle between the two modes. The button on the toolbar shows the current mode with a clock or a stopwatch. When showing duration the Time field in the output shows the number of seconds it took for the underlying file system to service particular requests. The Options|Show Milliseconds menu entry lets us add millisecond resolution to times presented when FileMon shows clock times. We can toggle FileMon to always remain a top window with the Options|Always On Top menu item. In addition, we can toggle FileMon not to scroll the listview via the Options|Auto Scroll menu item or corresponding toolbar button. Named Pipes and Mail Slots - Starting in version 4.1 FileMon is able to monitor named pipe and mail slot file system activity on Windows NT/2K. In addition, Filemon is free for us and it does not contain any adware or spyware, so we can use it safely and undisturbedly. It is a standalone software and does not need any extra software and hardware requirement. It works with most recent variants of Windows.
