Monitor LAN, control the usage of the Internet, and Network Resources

  Can I Monitor my LAN, control the usage of the Internet, and Network Resources by other computers from my main computer?

In order to monitor, or and Control Network traffic you need to be able to access and control a central point in the network that passes through all of the Network Traffic.

In the case of small Entry Level LANs that would be the Switch on a Cable/DSL Router or an independent switch if a Cable/DSL Router is not used.

Unfortunately Entry Level Routers or Switches are not equipped with the capacity to collect the information, and allow it to be read, and or controlled by one of the Network's computers.

There are few options to control the Network, or shared Internet activities on the Network computers.

Remove duplicate files the easy way

I have always wanted this kind of software. I have thousands of mp3 songs packed in various partitions of my hard disk. I have collected these songs from several places and keep them storing, but the problem while augmenting my collection is that I am never sure whether I have copied the set of songs before or not, so I just copy them irrespective of the fact that they may be already present. The consequence is that my limited 40GB hard disk space is almost full leaving me with no more space to store anything else.
That is why I always wanted a software that could compare the contents of two folders and remove the duplicate elements.
