As processes are loaded and removed from memory, the free memory space is broken into tiny pieces. Sometimes, processes cannot be allocated to memory blocks considering their small size, and memory blocks remain unused. This problem is known as Fragmentation.
Or we can say Fragmentation is storing a file in noncontiguous areas on your disk, and your storage space is used inefficiently, and thus your hard drive performance is reduced.
To improve your files' read and write speed, please performs the steps mentioned below:
Step 1. Search and locate defrag.
Step 2. Now select "Defragment and Optimize Drives" in the search result.
Step 3. Choose the hard disk you want to optimize and click the "Optimize" button.
