But this method merely "relieves" the symptoms that these files induce - it doesn't attack the cause. These files need to be deleted - not "organized!" Of course, deleting files can be a scary adventure to most users. Most computer users don't know which files are safe to delete and which aren't. You'll want to first, select the computers that will connect to each other and then install the network cards inside each of them. Then you'll connect a cable to each computer that will communicate with the server. These cables won't connect to the server directly. Instead, they'll connect to the router. You can monitor the conversations your children have with their friends and teach them appropriate online behavior at the same time. You can make recommendations and create a private time for quality time as well. The third step involves blocking access to inappropriate areas altogether. You and your children may not always agree about what's appropriate, but as a guardian, you're in control and you're ultimately responsible for their safety. You may find yourself in need of more hard drive space for all those videos and mp3s that you download, for example. Or maybe that cool new programming language you've been dying to try requires more memory than what your computer currently has. Unless the activities on your computer are restricted to pure textual output (plain text files), your computer is going to get filled with a lot of "stuff" - stuff that can overfill a PC's capacity too much for the computer to function well. One thing that you certainly don't want to use to remove computer dust is a vacuum cleaner. Although using a vacuum cleaner seems to make more sense, the strong suction of a vacuum cleaner can actually spark damaging static electricity or dislodge loose cables. You also don't want to use oil-based cleaners. Up until recently, public opinion held little faith in freeware or open source software - often regarding it as low-quality knock-off's of better known commercial products. But if you take a good look at what's being offered at no cost, you may be in for a big surprise. The quality of today's freeware and open source software created a strong rift among the commercial community and it's literally driving the competition bananas!
