OPTIMIZE is O&O Defrag's default method. It executes a SPACE defragmentation in all three zones of the selected
drive. The files will be so arranged in order to maximize the resulting free disk space. It is the recommended default
method because it works thoroughly as well as well as quickly.
OPTIMIZE/Quick
OPTIMIZE/Quick provides a speedy defragmentation requiring very little hard disk usage. It defragaments files in
all the different zones. It also moves files which are not located in the correct zone to the right one. This method is
new in that it aggressively reduces fragmentation of extremely fragmented files, without having to analyze the
entire file system.
OPTIMIZE/Complete
OPTIMIZE/Complete replaces or combines the properties of the previous COMPLETE-Methods. The user decides
which method should be run on each zone (SPACE or COMPLETE sorting). A new sorting of the data allows the
defragmentation to be done more thoroughly, but at a considerably slower pace than the standard Optimize
method. This method is only needed when, for example, you want to rearrange the files on a hard disk following a
large-scale program installation.
Standard defragmentation methods
In addition to the three new methods, O&O Defrag continues to offer its five older methods for defragmenting
your computer.
