What is defragmentation?
Defragging, or the defragmention of your computer, is the process whereby information and files stored on your hard drive are reorganized into a more logical order. The actual defragment process can slow your computer down, but once it’s complete, your hard drive should be considerably quicker and have more storage space on it.
How does defragmentation work?
However, solid-state drives (SSDs) should NOT be defragged, as it will reduce their lifespan in return for a negligible performance uptick. Make sure you know which kind of hard drive your computer has before defragging.
