Optimize and defragment drives

Disk defragmentation basically rearranges all the data spread across your hard drive and stores it together again. When files are written to disk, they are split into multiple pieces because there is not enough contiguous space to store the entire file. Thus, the files become fragmented. Naturally, reading all this data from different places will take some time, in short, it will slow down your PC, have long boot times, random crashes and freezes.

Defragmentation decreases file fragmentation, thereby improving the speed at which data is read from and written to disk. This ultimately increases the performance of your PC. Disk defragmentation also cleans the disk, thus increasing the overall storage capacity.
