Defragmentation is a process in which files stored on the hard disk are sorted and combined. Compare the hard drive or SSD to a shoebox in which you keep lots of notes (the files). Windows tears up any new notes and simply throws the snippets into the shoe box. If you then want to access a file again, Windows must first find the “file snippets” and then glue them together before the file can finally be loaded. This costs time and vastly reduces performance.
