O&O Defrag protects you from an inevitable fate when working with a Windows operating system - a slow down across the board. Why does this always seem to happen, even when you have ample memory? It's the way Windows works when you write or save something to a machine. It breaks up your work and throws the pieces (fragments) randomly into memory gaps. That causes delays getting to your work later, and it makes the machine use physical motions way too often, leading to erosion. ## What is O&O Defrag used for?
