OPTIMIZE
OPTIMIZE is O&ODefrag'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 sys-
tem.
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 defrag-
mentation 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 pro-
gram installation.
Standard defragmentation methods
In addition to the three new methods, O&O Defrag continues to offer its five older methods for defragmenting your com-
puter.
l STEALTH
l SPACE
l COMPLETE/Access
l COMPLETE/Modified
l COMPLETE/Name
All methods can be used on all drives, including volume sets, stripe sets with and without parity, etc., and are equipped
for best possible data security. This is achieved by their working together with the defragmentation routines integrated
into Windows, and guarantees that data will not be lost if your computer or network crashes, or if there is a power cut.
