Defrag Windows To Keep It Running Faster

Prevent system failure with the simple task of defragmenting Windows.

First, a little explanation of what fragmentation is.

Your hard drive stores files in clusters. Clusters are small areas of space on the disk made up of one or more sectors. Sectors are 512 bytes in size. The hard drive is physically divided into sectors and the Operating System uses one or more of these sectors to logically divide up the drive. When you save a file, it is saved in continuous (or contiguous) clusters.

For this explanation, let’s keep it simple and say one cluster equals one sector. For example, if your file is 1000 bytes, it will use two clusters right next to each other. The next file you save takes up the next clusters, and so on.

Let’s say you go back and edit that file several days later (presuming it’s a document), and make it bigger by typing more (wow, you sure type a lot); now let’s say your file has grown in size to 2000 bytes.

Now it needs two more clusters. But the clusters next to the original piece of the file are already used by other files, so Windows saves the extra part of the file (the part you added by editing it) to the next available free clusters which are somewhere else on the drive and not next to the original clusters where the file was saved.

As you continue saving files, installing programs, and adding to files, these parts of different files get scattered all over your hard drive. As you, or Windows, or other programs need to access these files, it takes longer and longer to open them because Windows has to look all over the hard drive for all the pieces of the file. This is called file fragmentation, and it slows down your computer. Sometimes only a little; sometimes a lot.
