What is the purpose of defragmentation utility?

The purpose of a defragmentation utility is to optimize the performance of a computer's hard drive by reorganizing fragmented data. Over time, files can become scattered across the disk, leading to slower access times. Defragmentation consolidates these fragmented files into contiguous sections, improving data retrieval speeds and overall system efficiency. This process is particularly beneficial for traditional hard disk drives (HDDs), although it is less relevant for solid-state drives (SSDs).
