O&O Defrag - 68
Output Type Explanation
Data Security and Integrity
O&O Defrag guarantees you complete data integrity and security. Only functions that are implemented in Windows by
the operating system itself are used for defragmentation and synchronization of all file accesses.
File attributes (Date, Time, System, Archive etc.) and the security settings for NTFS drives will not be changed.
Access rights also remain unchanged. In addition, only one file per drive will be processed at any one time. This
ensures that even in a worst case scenario, only one file will be lost (e.g. if there is a power cut). If you have more ques-
tions concerning data security, we can provide you with more information. Do not hesitate to contact us at: sup-

Supported hardware
O&O Defrag supports all hardware components that are supported by Windows. Please note the software require-
ments of the corresponding manufacturer.
As a rule: if you can access your hardware with Windows as you would a normal Windows partition, and this partition is
formatted using a supported file system, this hardware can be defragmented. Removable drives such as streamers or
CD-RWs are exceptions, since defragmenting them might not be useful. You can also set network drives as target for
defragmentation.
RAID
Striped-, Mirrored- and RAID5-Volumes: The advantage of these drive types lies in their superior speed, which on the
one side facilitates accessing and storing processes, and on the other hand offer a higher degree of data security.
O&O Defrag supports all known RAID systems. According to many hardware manufacturers, defragmenting RAID sys-
tems is especially important: as their files are spread over several hard disks, their fragmentation level is likely to be
very high.
Supported File Systems
O&O Defrag supports all Windows file systems. The following paragraphs will tell you more about each of these file
systems.
File System Explanation
exFAT Starting from Windows Vista, the exFAT-file system is supported.
This was designed especially by Microsoft in regard to flash drives,
and delivers better performance than FAT. It is also much better
against structural damage to the file system and protected against
data loss.
FAT
FAT is the oldest data system, the roots of which go back to MS
DOS. It is supported by Windows. O&O Defrag can be used without
any problem on FAT drives.
FAT32 FAT32 is the native file system of Windows 95b/98/Me. It offers some
