FAQ's about O&O Defrag V8.0

Here you will find the most frequently asked questions about O&O Defrag V8.0 - and of course the answers! This list is updated and extended at regular intervals.
 

General Questions

1. Is O&O Defrag V8.0 compatible with Windows XP?

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

3. But I thought NTFS didn't fragment? 

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

O&O Defrag offers you much more functionality than the Windows built-in defragger. You'll find full details of this here.  

5. I've heard that it can be difficult to restore deleted files with O&O UnErase after a defragmentation. Is this true?

However, you should note the following - especially on FAT-formatted partitions, the chances of successfully restoring your file are far greater if the partition has been regularly defragmented.

Technical Questions

1. 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 V8 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 V8. The functionality of these two administration tools is exactly the same!

2. 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? 

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. 

3. Which method 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 were last changed. This is especially suitable for data partitions on workstations, or for fileservers. 
• COMPLETE/Access organizes all files according to when they were 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.

4. 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.

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

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

6. Is O&O Defrag V8.0 compatible with a version of Windows XP running Service Pack 2?

O&O Defrag V8.0 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 V8.0 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 V8.0 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 labeled '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'.
     

Now you will be able to take advantage of the complete functionality of O&O Defrag V8.0 Server Edition.
