It is known to all PC users that a cleanup of the unnecessary files of the hard disk, followed by a simple defragmentation will significantly optimize pc performances, making it always run at top speed. But have you ever thought of what is the difference between them, which one should be done first? If not, please be kind to read this article for further information.

Essentially, Disk cleanup is a process that delete/remove the unnecessary files from the computer and then release more available space, but on the contrary, disk defragmentation will not delete any file from the computer, what it does is to rearrange the files on the computer, making them always stay at the same directory of the hard disk. Hence, it will shorten the time to access / retrieve the file, optimizing PC performance. So to optimize PC performance, please remember to always run a disk cleanup and defragmentation.

As we all know that when installing programs on the computer, there will be lots of junk files coming along, including some temporary files like *.tmp, *._mp and log files like *.log and the IE temporary files when surfing the internet, etc. These useless file will take lots of available space on the hard disk. So in order to always optimize the computer, please first run a disk cleanup to remove the unnecessary/ useless files from the computer, so as to free up more available space on the hard disk. You can simply follow the steps below to begin the deletion process: go to My Computer -> right click disk to be cleaned up-> Properties -> General -> Disk cleanup -> select the file types to be deleted within the appearing Disk Cleanup wizard -> Press OK and then Yes to automatically remove the junk files from your computer.

Besides, as we all know that when the first available free area to store a file is not large enough to store the whole file, the remaining part is saved on the next available free area, which goes on until the whole file has been written to the partition. Because larger files take more space to save, they probably will be more fragmented. If the fragmented files are used frequently by the system, it will take relatively a lot of time to read them, which will completely slow down the computer. So a defragmentation on the hard disk will defragment those files which can improve the system performance significantly. So it is necessary to proceed a manual defragmentation after the Disk Cleanup by the start menu, All Programs, Accessories, System Tools, sub Disk Defragmenter.

In order to always optimize the computer, please remember to regularly run a Disk cleanup and a disk defragmentation. If you have never done it before, please go to optimize pc performance with the method above.
