Fragmentation occurs on every computer. When files are saved, they are chopped up and stored in individual pieces on the hard drive or SSD wherever there is space. Defragmentation reverses this storage chaos. A defragmentation re-sorts the saved files and puts them back together. How does O&O Defrag help? O&O Defrag cleans up this shoebox by combining the snippets of a file and writing them one after the other to the hard drive or SSD.
