What is Disk Defragmentation? Why do I need it?

Disk defragmentation is the process of unifying fragmented files on your PC’s drive.

Fragmentation happens to a hard disk when you use your PC, install and uninstall the programs, and create and delete the files. For instance, you uninstall a program from your PC; it is removed along with its associated files, leaving the gaps on the drive. Now when you install new program which takes up more space than the deleted one, windows will store it randomly splitting into multiple pieces on your drive. Over time both the file and disk becomes fragmented more and more, slowing things down.

Defragmentation is an important maintenance task which reorganizes the files on your drive, making them more organized and quickly accessible.

What causes fragmentation?

Fragmentation is a state wherein the data storage is disorganized and unsystematic. There is no continuous or linear space on your hard drive is available, your hard drive is unable to store complete information in a sequential order, so disk takes more time to read the fragmented data back from the hard disk.

Fragmentation is caused by:

  • Less free space available – Whenever sufficient free space is unavailable to store the entire information, the storage is in parts in the hard disk.
  • Frequent deletions – Often, the unwanted data is deleted from the hard disk. In this process, free gaps are left in between fragmenting the hard disk.
  • Extension of Files – Additional changes made to the already stored files may not be stored in the same sequence in the hard disk in the absence of enough space. Usually in such case, the system creates an extension of the file and stores it somewhere else.
  • Moving of Data – There can be instances when data is moved to a new location and there isn’t enough space to store all the data. The information is then stored in pieces on the hard disk.

Why do you need to Defrag your hard drive?

When your Disk is in constant use for storing data, continuous deletions and uninstallations leaves small chunks of free space behind, no space is there for new files to be stored in their entirety, and your PC is compelled to store the data in small chunks of available free space.

All this makes the drive do extra work that slows down your PC. Fragmentation may cause PC slowdown, slow startups and shutdowns, low hard disk storage efficiency and declining performance. And you must defrag and optimize your drive to improve PC performance.

How can Advanced System Optimizer fix the issue of fragmentation?

Advanced System Optimizer includes a Disk Optimizer tool which rearranges your fragmented data so your hard disk can work more efficiently. Disk Optimizer tool has an in-built scheduler, and also you can also defragment your hard disk manually.

It scans your PC to find the fragmented data on your hard disk, and brings them together to reduce the data access time. It removes all the fragments from the hard disk by gathering all the small chunks of free space together.
