Disk tools perform a variety of tasks with the hard drives in your PC. This can be creating and deleting partitions (EASEUS Partition Master, AOMEI Partition Assistant) creating bootable media (WinToFlashLite or Rufus) or defragmenting.
Defragmentation programs are system tools that are used to analyze local hard drives in order and to consolidate fragmented files or folders. You should know that all versions of Microsoft Windows, starting from Windows 3.11, have a built-in defragmenter. There are also, sometimes much better, stand-alone defragmenters, such as Defraggler and JkDefrag.
What is defragmentation?
Defragmentation is the process of consolidating fragmented information on the disk. It allows the system to operate better and more efficiently. Defragmentation is performed on hard disks. At the same time, it should be borne in mind that on SSDs and media with a Flash memory cell this process does not make sense due to the lack of delays in reading and writing. Defragmentation, in this case, may damage the disk (due to the increased consumption of Flash cells) and shorten its lifespan.
During defragmentation, the computer groups files and move them into one place. After the process is completed, the risk of data loss decreases, and just as importantly, in the event of a failure, the information can be retrieved much easier and faster.
Defraggler is an example of a defragmentation program. The software is developed by the Piriform company (they are the creators of CCleaner) and it is available for free for private use, while you need to pay for it if you plan to use it with commercial intent. The application allows you to defragment entire disks or just the free space. You can also choose files or folders. It is also possible to run the program from the command line. Defraggler displays disk information. It is able to work on Windows XP and newer systems from the Microsoft family.
Other notable defragmenters are IObit Smartdefrag, JkDefrag, MyDefrag, PageDerfag and Auslogics Disk Defrag Free.
