Which process reorganizes files in storage for faster access?

• A. Defragmentation
• B. Compression
• C. Disk Cleanup
• D. File Management

Answer: (A)

Defragmentation focuses on reorganizing data on a storage device so that the pieces of each file are stored contiguously. Over time, as files are created, moved, and deleted, their blocks can become scattered across the disk. When the system reads a file that’s fragmented, it has to move the read head (or seek) to many different locations, which slows access. Defragmentation analyzes the disk, moves the fragments so each file’s pieces sit next to each other, and often groups free space together to reduce future fragmentation. The result is faster file reads and better overall performance on traditional hard drives, since the system can read each file in fewer seeks. Compression reduces file size, Disk Cleanup removes unnecessary files, and File Management is a broad term for handling files; none of these reorganize the physical layout to speed access in the same way.
