Fragmentation, in the context of a hard disk, is a condition in which the contents of a single file are stored in different locations on the disk rather than in a contiguous space. This results in inefficient use of storage space as well as occasional performance degradation. Users frequently create, modify, delete and save files. Back-end operating systems (OS) continuously store these files on hard drives, which inevitably create scattered files. When fragmentation occurs, the OS needs to consolidate stored files to enhance processing efficiency.
