Tips for optimizing your performance
Defragment your system regularly!
Only defragmentation on a regular basis can ensure that you always get the best out of your
system! O&O Defrag offers you the best way of planning an optimum defragmentation of
your system.
Don’t wait too long before you defragment!
As soon as you’ve installed your operating system, the file system will begin to fragment.
Avoid reduced performance right from the beginning and install O&O Defrag in good time!
Only then can you be sure that your hard disks can access your files quickly. You will also
avoid unnecessary wear and tear on your hardware due to increased movement of the read/
write head.
Large files need more free hard disk space
If you want to defragment large files, you need more free hard disk space. For reasons of
data security, the original (fragmented) file remains on the volume until the defragmented
copy has been safely saved to disk. We recommend you have at least 5% free disk space – if
you have more, this will speed up the defragmentation. For modern hard disks having more
than 100 gigabytes, this value can be significantly lower.
Avoid moving large numbers of files during the defragmentation
If you are using the SPACE or COMPLETE methods, O&O Defrag will calculate the best
position for your files before and during the defragmentation. If you copy, move or delete
files, these calculations will have to be carried out again. This will take time and lengthen the
defragmentation time. Please keep this in mind!
Automatic defragmentation with the threshold tool
Along with its default background monitoring, O&O Defrag offers you the option of automatically
defragmenting your system with a time schedule. You can additionally increase
your system’s performance by defining threshold values for your defragmentation. This
means that defragmentation will only take place when a particular degree of fragmentation
is reached. You can thereby avoid unnecessary defragmentation runs. In the job dialogue
under Drives, just enter a degree of fragmentation, e.g., 5%, upon which the job should be
run.
Using O&O Defrag on your notebook
We have introduced a new power management in this latest version of O&O Defrag. This
allows you to suppress defragmentation runs when your notebook is running from battery
power. The length of your battery’s life will therefore not be affected and you won’t have to
stop the defragmentation manually. O&O Defrag recognizes the switch between main and
battery power and will run the defragmentation according to your own configuration. You
can read more on this in the section about Settings.
