A utility to optimize hard disk performance by rearranging files and consolidating free space, resulting in faster read/write times.
Windows Disk Defragmenter is a hard drive optimization utility that has been included in Microsoft Windows operating systems since Windows 2000. It helps improve hard drive performance and speed up read/write times by rearranging files stored on a volume and consolidating the free space.
As files on a hard disk drive become fragmented over time from saving, deleting, editing, etc., the fragments get scattered across different areas of the disk. This requires more movement of the hard drive heads to access file fragments, slowing down access and write times. Disk Defragmenter works to clean up this fragmentation by moving files around so that all pieces of a file are stored sequentially in one place, in what are called contiguous blocks.
By optimizing file order and consolidation, Disk Defragmenter can speed up data access and help applications and files launch and open more quickly. It's useful for helping boost system performance and responsiveness over time as fragmentation naturally occurs. Running Disk Defragmenter periodically can be beneficial for maintaining efficient disk operations.
