UltraDefrag
UltraDefrag is a powerful Open Source Defragmentation tool for the
Windows Platform. UltraDefrag speeds up the computer by defragmentation
of files. When files consist of many little fragments scattered around
the disk the computer needs more mechanical work to read them. Because
of that the disk access becomes slower. UltraDefrag reduces the file
fragmentation, thus it makes disk operations faster. Also the program
can optimize a whole disk placing all the files to the fastest part of
the disk - to its beginning. In contrast with the most other disk
defragmenters UltraDefrag can defragment locked files by running during
the Windows boot. Actually all files including registry hives and
page-file can be defragmented there. Also UltraDefrag aims to be fast,
simple, reliable and efficient. Available for 32 bits and 64 bits Windows, and also as portable

O&O Defrag
If you work on computers a lot, then slow system and
program starts, endless rendering and memory processes, or even system
crashes when playing can quickly ruin your enjoyment. Defragmenting
your PC can hugely accelerate the speed you can work on your PC. When
you defragment, those files fragmented across the hard disk are
logically rearranged so that files can be quickly recognized and
processed by the hardware. Performance gains of up to 100% are not
uncommon!
O&O Defrag Free Edition merges fragments that were created while
Windows was saving files. Merging them increases your computer’s
performance considerably. On top of that, the “Optimize”
defragmentation method consolidates free space on your hard disks so
that new fragmentation can be kept to a minimum.
Intelligent zone filing makes it possible to move your files into
various physical sectors on a hard disk. As a result, frequently-used
files can be saved on the fastest sectors of the hard disk and this
improves your computer’s performance even further.
