defragmentation
when you defrag a computer the basic way to put it is it will be looking through all of your files and it will find empty or unused files that are taking up space that could be removed and it deletes them for example if you had a folder called videos and in that folder you had two folders one called bad videos and good videos but you have found alot of videos you do not like but none that are good if you defrag the computer it will find this unused file that is taking up space and it will remove it so this is how defragmentation can help speed up and free space on your computer
