4. My computer has finished the defragmentation process. Why does O&O Defrag still show a fragmentation degree of more than 0%?

The reason might be one or more fragmented files, which are locked during run-time. Thus O&O Defrag can not defragment this file.

Running a boot-time defrag with O&O Defrag might solve this problem, as the file(s) are not locked before the system starts and O&O Defrag can Defragment these files, too.

Another reason might be a lack of contiguous free space available on your hard disk partition. If the fragmented file is bigger than the biggest piece of continuous space available, it is physically not possible to defragment the fragments. You might try to consolidate as much free space as possible by using the SPACE method O&O Defrag offers.

5. How do I check my hard disk fragmentation status?

Simply install your copy of O&O Defrag and run an analysis on the desired drive(s) you wish to have analyzed. After the completion of the analysis O&O Defrag will show the fragmentation status for each of the drives.

6. How do I make O&O Defrag detect new fragmentation?

O&O Defrag allows you to define 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 and you are assured your drives are in optimal "shape".

7. My defragmentation run with O&O Defrag is taking a long time. Is this normal?

If you have not used a defragmentation software such as O&O Defrag for a long time on your system, your files may well be badly fragmented and O&O Defrag will have a lot of work to do to optimize all of your files. You can follow the defragmentation process using the graphical interface of O&O Defrag.

8. What is O&O Defrag 11?

O&O Defrag is the technologically leading defragmentation solution for Windows based computers. The software solves the performance and stability problems of Windows workstations and servers caused by fragmented hard disks.

Fragmentation is the main cause of significant losses in performance in Windows. Due to the fact that the hard disk is the slowest component of a computer, its optimization is an especially important issue.

By using O&O Defrag, files can be read and written much more quickly. What at first seems to be lost performance can easily be rediscovered and realized again with O&O Defrag, giving you the peace of mind that your hardware is in good health and operating optimally. New technological developments also ensure you are getting the best efficiency at the lowest cost.

9. Is O&O Defrag safe to use?

O&O Defrag uses 100% Microsoft Windows API’s to move and rearrange data and files. Thus performing defragmentation processes with the software is as safe as running the Windows system itself and for example moving a file with the Windows explorer.

10. For whom is O&O Defrag 11 Professional Edition intended for?

Please note: If you can access the storage system in the manner of accessing a Windows file system partition and this partition is formatted with a file system supported by Windows, O&O Defrag is able to defragment this storage device.

15. Do I need to uninstall an earlier version of O&O Defrag before I install the latest update?

Yes. Updating to a new release of O&O Defrag can be done both quickly and simply.

Microsoft Software Installer 2.0 or higher: Start the setup of the new release. / A screen comes up, in which you can choose to modify, repair or remove the program. / Choose Repair program and click on Next. / The new version is being installed. Previous settings will automatically be retrieved.

Please note: O&O Defrag 11 Professional Edition and O&O Defrag 11 Server Edition cannot be installed on computers running Windows 95/98/ME/NT.

17. Is the defragmentation secure? What happens if, for example, the power supply is interrupted during the defragmentation process?

To read and write files, O&O Defrag 11 only accesses the Windows APIs. Therefore, your data is completely safe.

18. But I thought NTFS didn't fragment?

Every file system fragments. Microsoft has now also recognized that NTFS does fragment, and even includes a built-in defragmenter in the latest Windows versions. If you want to test whether your hard disk contains fragmented data, just download the free test version of O&O Defrag 11 and carry out an analysis of your hard disk.

19. Newer Windows versions already include a defragmenter. Why do I need O&O Defrag as well?

O&O Defrag offers you much more functionality and better results than the Windows built-in defragger. You'll find full details at http://www.oo-software.com/en/products/oodefrag/

20. I've heard that it can be difficult to restore deleted files after a defragmentation. Is this true?

Any write access to the partition which contains your deleted file could endanger your chances of restoring it. You should therefore avoid write access. This includes defragmentation jobs and manual defragmentation, which you should avoid before restoring your file. However, you should note the following: the chances of successfully restoring your file are far greater if the partition has been regularly defragmented. You can find further information about restoring deleted files at http://www.oo-software.com/en/products/oounerase/

21. What's the difference between administration with the O&O Defrag Container and the O&O Defrag MMC?

The Microsoft Management Console (MMC) is an application that provides a unified user interface for various operating tasks. Administrators can thereby create a single application through which they can complete all administration tasks. The MMC itself has no functionality - it simply provides a common user interface for various tools (user account administration, services administration etc.) The O&O Defrag MMC Snap-In can be integrated into this console with no problems at all.

Users who prefer not to use the MMC can run O&O Defrag 11 locally without it. To facilitate this, we have provided you with a special container which reproduces the necessary functionality of the MMC in order to administrate O&O Defrag 11. The functionality of these two administration tools is exactly the same!

22. When I start O&O Defrag, my firewall tells me that someone is trying to access my hard drive. How can I solve this problem?

The communication between the components of O&O Defrag (e.g. the Agent and the GUI) is based on TCP/IP. This communication takes place only internally, and doesn't access the internet. However, most firewalls are programmed to recognize internal IP communication, so you receive a warning message.

You don't have to turn off your firewall! Simply open up port 50300. Since O&O Defrag automatically checks access privileges, there can be no external access over this port even if you are connected to the internet.

23. O&O Defrag offers five defragmentation methods. Which one is the right one for me?

O&O Defrag offers you five different methods of defragmentation in order provide the optimum defragmentation for your system, however it's used.

The STEALTH-Method is recommended if you want to defragment a hard disk that is nearly full (only around 8% free space). Due to its design, STEALTH is also the method that takes up the least resources.

The SPACE method is the standard defragmentation mode. It defragments all fragmented files and ensures that consecutive free space is maximized. This method should be used for the regular defragmentation of partitions that are within the normal range of usage.

As well as defragmenting fragmented files and maximizing consecutive free space, the Complete methods overhaul the position of your files.

COMPLETE/Name organizes all files according to filename and directory position. For example, all files that are in the directory Windows/System 32 will be placed next to each other on the hard disk. This method is particularly recommended for system partitions on Windows workstations.

COMPLETE/Modified sorts all files according to when they where last changed. This is especially suitable for data partitions on workstations, or for fileservers.

COMPLETE/Access organizes all files according to when they where last accessed. This method is particularly recommended for web servers.

These descriptions are intended only as a guide. An exact recommendation as to which method is suitable for which disk is impossible, because a completely accurate description of disk usage can hardly ever be provided. For example, data are often saved on what is actually the system partition.

24. Will my jobs run even if no user is logged on to the system?

Yes! The O&O Defrag Service runs independently of the current user, and starts a job even if no user is logged on.

25. How can I use O&O Defrag in Screen Saver Mode?

O&O Defrag can be instructed to always start when the screen saver is active. This will allow O&O Defrag to run automatically when your computer is idle. This option can be activated by creating a new job and selecting the option "Screen Saver Mode". All other configurations will be handled automatically by O&O Defrag. Please note that O&O Defrag will only run when the screen saver is activated in Windows. More information on activating the screen saver can be found in the Windows help file. As soon as the screen saver is ended (through user activity on the computer), O&O Defrag ceases operation. When activated again, either manually or automatically, O&O Defrag will continue from where it left off.

26. Can I close the user interface after I've started defragmenting?

Yes. The GUI is not necessary for the actual task of defragmenting.

27. Is O&O Defrag 11 compatible with a version of Windows XP running Service Pack 2?

O&O Defrag 11 takes advantage of the TCP/IP protocol for communication between individual parts of the program's operation. The integrated firewall in Service Pack 2 (SP2) can, among other things, hinder this communication.

If you are using O&O Defrag 11 Professional Edition locally and have SP2 installed with its default settings, no operation issues or problems should arise.

However, if you are administering O&O Defrag with the help of the O&O Defrag 11 Server Edition remote and have SP2's firewall activated on the client system using the default settings, no communication or remote administration will be possible. To remedy this, please carry out the following changes on the client system:

1. Open the Control Panel.
2. Double-click on the 'Windows Firewall' icon.
3. Switch to the tab labelled 'Exceptions'.
4. Click on 'Add Program...'.
5. Click on 'Browse'.
6. Navigate to your '...Windows/System32' Folder.
7. Select 'oodag.exe'.
8. Click 'OK'.
9. Check the box next to 'oodag.exe'.
10. Click 'OK'.

In order to change this setting on a large number of computers, please contact our Support at support@oo-software.com. Should you require it, we can provide you with the necessary tools to assist in this process.

28. Why does the background monitor not start-up on external storage volumes?

The background monitor will only start-up on your hard disk, not on external storage volumes. This helps avoid inconsistencies and data loss, which can occur if the storage volume is removed accidentally from your computer during an active background fragmentation.
