What does the Disk Defragmenter utility do?
Disk Defragmenter Overview The process of finding and consolidating fragmented files is called defragmentation. Disk Defragmenter consolidates the fragments to one location on the disk drive. As a result, Windows accesses files faster, and new files are less likely to be fragmented.
What is defragmentation and why do I need it?
Defragmentation organizes storage on your computer by consolidating files and other data saved on your hard drive. When there’s not enough space on your disk to store an entire file in one place, the file is broken down into smaller pieces called fragments. Defragmentation puts those pieces back together.
Is it safe to do defragmentation?
Even if you interrupt the process somehow, it’s not likely that your hard drive will suffer any harm. Defragging is one of the safest and simplest ways to care for your hard drive and ensure your PC is optimized for its best performance.
Does Disk Defragmenter improve performance?
Regularly running the Disk Defragmenter utility improves system performance. When the computer saves files, it fragments the files into pieces and saves the pieces in various locations on the hard drive. Windows takes longer to access files because it requires additional disk drive reads to find the pieces.

How often should I defrag my computer?
If you load, save and add to files on a regular basis, your system might require more frequent defragging than someone who only turns on their computer every few days. Most people should defrag their hard drives about once a month, but your computer might need it more frequently.
Do you lose data when defragmenting?
Normally, a defrag operation will not cause data loss. Unfortunately, if there’s a pre-existing problem, a defrag could bring data loss to the surface.
