File Watcher Utility
By Prashant Brall

The FileWatcher utility is cool tool to see changes to a file(s) in a particular directory. Whether it is a log file creating by some batch processing program or a report file generated by a reporting engine. All you have to do is specify the path and the type of file(s) you are looking and this program will automatically fire events on creating / renaming / deletion of files.

Functionality wise it is something sort of Acorbat Distiller. :) Happy dot Netting !!!
