When you try to access that file in the future, the read/write head of the hard disk drive has to move to different sectors of the HDD to gather bits and pieces of the file before rendering it. If the size of the file is bigger than that space, it writes the remaining portion of the file in another sector. The next time you install another program or store files, they get stored in the first empty space (sector) available in the HDD. When you delete files or uninstall a program, it leaves an empty space on the computer’s hard disk drive HDD. When you install a program in a newly configured computer, it writes the information in a systematic way on its hard disk drive.

It might be due to fragmentation of your drives and outdated entries in the Windows registry.įirst, let us understand what fragmentation is all about.
