Defragmentation
You can defragment your drives either parallel or sequentially. Sequential defragmentation
means that one drive will be defragmented after the other, in alphabetical order.
If you choose parallel defragmentation, drives (partitions) that lie on physically separate
hard disks can be defragmented simultaneously. This makes for a much faster defragmentation.
If you only have one physical hard disk in your computer, your volumes will be defragmented
sequentially.
Only in Windows XP and Windows Vista: During defragmentation, the Layout.ini-File is
used as a reference to optimize the layout of files on the hard disk. When you select to take
into account the file Layout.ini during defragmentation, O&O Defrag will defragment according
to the order of system files dictated by the operating system. Doing so can accelerate
the speed at which these files are loaded during a system's startup.
Power Management
Power Management is a special feature designed for notebooks. Using it, you can make sure
that defragmentation will not take place if the notebook is working from battery power. This
means your notebook’s battery will last longer. The notebook will only be defragmented
when it is reconnected to the main power.
If your computer is switched off, O&O Defrag can "wake" it from standby mode in order to
run a defragmentation. You can therefore defragment at night or on the weekend without
having to leave your computer running all the time, and without your having to be present!
