Notes about the DKB file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The DKB file type is primarily associated with 'DataKeeper' by Symantec Corporation. DataKeeper is included with PartitionMagic 8.0 and is required by Drive Image 5.x. Norton PartitionMagic 8.0 and PartitionMagic 8.0 (without the Norton name) are two different versions of the same product. DataKeeper is included with PartitionMagic 8.0, but it is not included with Norton PartitionMagic 8.0.
