Hello Mahesh, I did not know that you use the old version. Actually, Gnome VFS is deprecated, but on your Linux it should be still available. This library has a similar monitor: https://developer.gnome.org/gnome-vfs/stable/gnome-vfs-2.0-gnome-vfs-monitor.htmlProbably, this should suit you the most. There is also another library that you can try to use: http://en.wikipedia.org/wiki/Inotify If you do not want to add additional libraries (I assume there are more solutions like proposed above), you can write a custom function to get information about the file in the main loop or in a separate thread. If the information, such as changed date and size, changes, you can send a custom event.
