O&O Defrag V8.0 Professional Edition V8.0 - User Guide and FAQ

Frequently Asked Questions - O&O Defrag V8.0 Professional Edition

1. Is O&O Defrag V8.0 compatible with Windows XP?
   Yes, it is.
   
   
2. 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 V8.0 only accesses the Windows APIs. Therefore, your data is totally safe. With NTFS, an interruption in the power supply can't damage your data anyway.
   
   
3. 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 V8.0 and carry out an analysis of your hard disk.
   
   
4. I've heard that it can be difficult to restore deleted files with O&O UnErase 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 - especially on FAT-formatted partitions, the chances of successfully restoring your file are far greater if the partition has been regularly defragmented.
   
   
5. 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!
   
   
6. 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.
   
   
7. 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.
   
   
8. Can I close the user interface after I've started defragmenting?
   Yes. The GUI is not necessary for the actual task of defragmenting.
