Detailed explanation-1: -Disk fragmentation occurs when files or pieces of files get scattered throughout your disks. Not only do hard disks get fragmented, but removable storage can also become fragmented. This can cause poor disk performance and overall system degradation.
Detailed explanation-2: -The purpose of fragmentation is to help an operating system use the available space on a storage device. In the absence of disk fragmentation, application and file storage need to continuously be updating and moving storage blocks, in order to maintain a continuous, non-fragmented file system.
Detailed explanation-3: -Defragmentation is the process of consolidating fragmented files on the user’s hard drive.
Detailed explanation-4: -Microsoft Drive Optimizer (formerly Disk Defragmenter) is a utility in Microsoft Windows designed to increase data access speed by rearranging files stored on a disk to occupy contiguous storage locations, a technique called defragmentation.
