When you make changes on your PC, the data is stored on your hard disk.  Anything you are likely to do on your PC, such as using copy, paste, delete and even saving files will result in disk fragmentation.  The files that you modify are stored in a separate segment on the hard disk from the original file location. This is where, over a period of time, your system can slow down and become unresponsive, because your computer is looking in different places to open a file.

Defraggler

Defraggler is a great tool to freshen up your PC

A great tool for defragmenting your hard drive is Defraggler.  It is a free application that offers you various different options to defragment the hard disk. The application is actually better than Windows’ native defragmentation tool!  When you open Defraggler, if you navigate to Settings and then Options, you will find plenty of different options to tweak. You can exclude certain files from being defragmented.  This can be done according to drives, folders, file or file type.  If you want to, you can also schedule the defragmentation to occur at a particular time daily, weekly or monthly.

To start off,  you need to inform Defraggler which drive you want to scan (usually C:) and click the Analyze button.  This will check to see if you actually need to defragment your disk.  The results are displayed in a Drive Map graphic and text.  If the drive needs to be defragmented then just click the Defrag button to begin the defragmentation process*.  You will see the progress in the Status section.  Once the process is complete, you can restart your computer with a freshly defragged hard drive.  That’s it!

You can download Defraggler from FileHippo.com today.

*During the defragment process your computer will slow down.
