How do I defragment my hard drive

Windows Defragment hard drive under Windows - this is how it works


Normally, the hard disk does not have to be defragmented under Windows, as the operating system takes over this task automatically. Fragmentation means that the contents of a file are scattered across the hard drive. This happens every time you open a file. Because the new data in a file is saved on the hard drive where there is currently space. If your hard drive is extremely full, Windows may have problems with the automatic defragmentation and cannot reconnect the file parts that belong together - you can help manually.
