O&O Defrag

I recently tried a new defragmenting software I am writing about some of its features here .I like it because its interface is neat, it does the job in more efficient manner than Microsoft?s own defragger does

Fragmentation: Causes and Effects

Fragmentation results from saving your files on your hard drive. When files are saved, Windows automatically looks for free space and saves the file accordingly. Sometimes, however, there is not enough contiguous free space on the storage volume to save the file into a single block. This happens whenever files are created, modified, or deleted. When you delete a file, the space occupied by this file is marked as free, opening up this space for new files to be saved. If a new file does not exactly fit into this spot, Windows splits the file up into fragments and stores them in different locations on the storage volume. When you open the file, Windows first has to find all the fragments, load them, and then put them back together. This process can be very time consuming, especially if you create or get rid of files often.

Regular Defragmentation is the Only Solution

Even in the age of fast and affordable hardware, an important part of a system?s performance is dependent on the operating system used and its integrated file management. The most frequent problem is file fragmentation. Files are separated in multiple single fragments and distributed over the user's hard disk. As a result, processing these files takes much longer, because all segments belonging to one file have to be relocated, read, and reassembled. The impact is particularly dramatic in Windows - the longer a system is in use, the more intensive file fragmentation, inevitably causing performance losses. O&O Defrag rediscovers this lost system performance, saving both time and money.

File and database servers, as well as workstations can substantially improve their system performance using O&O Defrag V8. Regular defragmentation prevents new hard disk fragmentation and will ease the use of Windows XP/2003, Windows 2000 and Windows NT 4 in the long term.


O&O defrag has many modes each of one is shortly explained below




The STEALTH method is based on our unique STEALTH technology; allowing an unprecedented level of defragmentation on computers with a large number of files, little free space or available central memory.

This method defragments all fragmented files and tries to consolidate them in order to optimize available free space. Here, speed and resource usage are the main considerations and the method is therefore not quite as thorough as the SPACE and COMPLETE methods.


All fragmented files will be defragmented, and then placed into the free slots in which they fit.

This maximizes contiguous free space. This method is very quick and efficient and it does reorganize your volume, but not as thoroughly as the COMPLETE methods.

Further defragmentation will not be affected by the SPACE method. The SPACE method is ideal for the first defragmentation run on a system that has never been defragmented, as it requires far less free space than the COMPLETE methods.


Files are sorted according to when they were last accessed. The files that have been accessed the least will be placed at the beginning of the partition, and those that are accessed that most frequently are put near the end. Seldom-used files are defragmented and will not need to be moved in future. Frequently-used files are placed at the end of the volumes. This strategy means that future defragmentation runs are as quick as possible, as fewer files need to be checked and defragmented.



Files are sorted according to the date on which they were last changed. The files which have not been changed recently are placed at the beginning of the partition, and the files that have been changed recently are placed at the end. This option is a good one for file or database servers which contain files that have never been changed (e.g. system files), but where others are frequently modified. (e.g. database files)

This strategy means that future defragmentation runs will be much quicker, as only a few files need to be checked and defragmented.


Files are sorted alphabetically from the beginning to the end of the partition. This leads to quick access to files in a directory. When Windows starts up, many system files will be read in sequence from the \WINDOWS and the \WINDOWS\system32 directories (DLLs, system drives, etc.) and the start-up time will therefore be shorter.

This method is particularly recommended for computers on which the files rarely change. This reduces the reorganization time that is needed for every defragmentation.


Analyzing Your Volumes

Analyzing your hard disks gives you an overview of how heavily fragmented they are. O&O Defrag creates a detailed status report about the fragmentation level once the analysis has been completed.

This level will be somewhere between 0 and 100 ? the lower the number (zero is the ideal), the less fragmented your hard disk. A value near 100 is the worst case ? your files are almost completely fragmented. Even values of around 30 mean that the performance of your system is seriously suffering from the level of fragmentation, and that a defragmentation run is strongly recommended.


Level Explanation and action needed

< 10 All files are almost completely defragmented. This is the ideal condition and can only be achieved and maintained through regular defragmentation.

10 ? 30 This level is reasonable, and means that your hard disks are in good condition.

31 ? 50 Your system is working more slowly than normal because of heavy fragmentation. Defrayment regularly and use the time planning facility included in O&O Defrag. This will keep your system running at a good speed.

51 ? 90 Your system is very heavily fragmented and is suffering from very serious performance losses. You should Defragment your system right away and create jobs for regular defragmentation. Compare the fragmentation levels before and after the defragmentation run.

> 90 Almost all of your files are fragmented ? you?ve probably never, or very seldom, defragmented your system. The effect on your system is dramatic. Defragment your hard disks frequently, and bear in mind that it might take several runs before an ideal fragmentation level is reached.

Starting an Analysis


Select the volume to be analyzed in the volume list.


Start the analysis via the toolbar or from the context menu (select "Analyze?). The analysis can take a few moments, even if the volume is small. You can follow the progress of the analysis on the volume symbol and the progress display.


When the analysis is finished, a dialog window with a summary of the volume information will be displayed. You can display the detailed status report as a HTML document in your web browser.

Note: You can analyze several volumes simultaneously. Mark the various volumes by keeping the Ctrl key depressed whilst selecting.



Defragmentation Execution

You can defragment your volumes either parallel or in sequence. Defragmenting in sequence means that the volumes will be defragmented one after the other in alphabetical order.

If you choose parallel defragmentation or volumes that lie on physically separate drives (partitions) will be defragmented at the same time. This significantly speeds up the defragmentation. If you only have one physical hard drive on your system, the volumes will be defragmented in sequence.

Power Management

Power management is especially intended for notebooks. You can specify that defragmentation should not take place when the notebook is running on battery power. When the notebook is reconnected to the mains power, the defragmentation will automatically be resumed.

If your computer is switched off, it can be roused by O&O Defrag out of standby mode to carry out the defragmentation. You can thereby defragment at night or at the weekend without having to be physically present or leaving the computer on.

Notice from BuffaloHELP:
It's clever that changing few words here and there is bypassing the plagiarizing but you are still copying the words from another site. Source http://www.northern.net/ The whole post is still under review. After confirming QUOTEs were not used, a warning will be issued.


Second source http://www.majorgeeks.com/ And when I see The STEALTH method is based on our unique STEALTH technology I know you didn't write this. Warning issued.

I remembered it's name now. It's called "mst defrag". It doesn't only defrag when you tell it to defrag. The program keep track of changed files in background and will start defragging when the computer is idle. This is what it keep my old computer boot time quicker that the avarage old computer. (I boot it yesterday to get some fonts from it)
