User's guide O&O DiskImage General Terms and Definitions
File format OMG
O&O DiskImage generates the file extension (*OMG) for the image files it creates when imaging
your entire computer or single drives. This file type can be used for further activities by O&O
DiskImage, such as restoration, validation or conversion.
File format OBK
While creating a file backup using O&O DiskImage, the files and folder are compressed and stored
as OBK file (*.obk).
File format VHD
O&O DiskImage is able to create and edit file formats for virtual computers (VPC/VM-Ware). This
allows you to also mount a drive from an image as a virtual drive in the VPC or your VM-Ware.
File format VHDX
This further enhances the options for virtual environments. The main advantage of VHDX is its
increased storage capacity of 64 TB (terabytes), instead of VHD's standard storage limit of 2 TB.
Another advantage of VHDX is the file corruption protection.
Complete image
Using the Complete image method, the data selected for imaging will be imaged all over again and
stored in a folder on the target disk. Complete images can be created using the "Used sector",
"Forensic", or "Direct forensic" methods.
Differentiation: Image of the changes
If you only want to image changes of your hard disk or drives, you will need to have created at
least one complete image previously. Changes made can then be saved as differential and
incremental images.
