Which tool within SMART helps in organizing files to improve drive performance?

The correct choice, defragmentation, is a tool that significantly enhances file organization on a hard drive. Over time, as files are created, modified, and deleted, they can become fragmented, meaning that the individual pieces of a file can end up scattered across the physical disk. This can slow down read and write operations since the drive's read/write head has to move around to gather pieces of a file from different locations.

Defragmentation works by reorganizing these scattered pieces of files into contiguous blocks of space. This process reduces the movement required by the read/write head, leading to improved performance, especially for traditional hard disk drives (HDDs). While modern solid-state drives (SSDs) do not require defragmentation and can be negatively affected by it, the concept is vital for understanding HDD performance.

The other tools listed serve different purposes. Compression reduces the size of files to save space but does not directly improve performance. Disk Cleanup helps to remove unnecessary files to free up space but does not address fragmentation. File Recovery is concerned with retrieving lost data rather than optimizing file organization or drive performance.
