How to DeFragment the files on your Computer disk drive- Clean my PC Free.

Performance and the efficiency of your computer can be greatly improved by defragging the drive.

This is a straight forward and an easy task to achieve. Adding and deleting files from your hard disc may be a common task. Writing and deleting records from your hard drive might be a typical job. This process isn't constantly done proficiently.

When you erase a lot of little files and include another enormous file, the file may get separated into multiple areas on the hard drive. The PC will at present seek the recently included file as a solitary legitimate one, yet the read-write arm will check various pieces of the drive to access it. This can decrease your PC's speed considerably.

In the event you have a huge load of "divided" records on your hard drive, you may hear additional noises originating from your PCs' drive as the read-write head travels backwards and forwards looking for the data.

A fragmented drive is slow to open files so regular maintenance is a good start. This is just to give you an idea as to what fragmenting is. Imagine your drive as a clock face, the space between the hours are known as sectors. Now imagine each hours space is divided up into say, 10 blocks. These blocks are the tracks.

When your computer writes a file to disk, it finds the next best empty track and fills it with your file. Then, the system writes the details of where that file is on the disk into a file allocation table. If on the other hand, the file you are writing is too big for that space, it splits it up and places the next part of the file into the next best space, thus, your file is now fragmented. What defragmenting does is, to gather all the file parts into a temporary space and rewrite them all into new consecutive spaces and therefore, speeding up the search and retrieval.


If you are unsure which type of drive you have, Click in the search bar at the bottom left hand of your screen, type "dfrgui" without the quotes and press enter. When the new window has opened, it shows your drive or drives installed on your PC.

If you have more than one drive installed, scroll down the list to find the Windows system drive, it usually has a tiny light blue icon with four dots on it and it is usually the C drive. There you will see the type of drive you have either, a hard disk drive or solid state drive. Click close when done.
