OO Defrag Professional Edition v12.0.197 x32 / x64

Fragmentation can drastically slow down your computer. But the situation is
not hopeless: O&O Defrag is the perfect remedy! Defragmentation rearranges
the individual data fragments and writes them contiguously on the hard disk.
This is really the only way for your computer to regain its original power
and performance.
O&O Defrag 12, however, goes one step further. All your systems files will
be sorted according to their level of use, and each one will be separated
into its own section of the hard disk (drive zones). O&O Defrag 12
introduces 3 new defragmentation methods that can also apply a user-defined
classification of files to perfectly complement all previous methods.
O&O Defrag 12 is everything superior defragmentation software should be: it
gives you fully automatic defragmentation for the home user as well as
expert-level professional setting options.
