We continue highlighting new features that will make their way into Windows 10. This time we’re informing you about a minor, yet important feature for some power users – new DISM options.
For those who are not aware, DISM stands for Deployment Image Servicing and Management (DISM.exe) and is a command-line tool that can be used to service a Windows image or to prepare a Windows Preinstallation Environment (Windows PE) image.
DISM can be used to service a Windows image (.wim) or a virtual hard disk (.vhd or .vhdx) and it replaces the ImageX tool which was deprecated in Windows 8 as well as the Package Manager (Pkgmgr.exe), PEimg, and Intlcfg.
And it seems that with the Windows 10 release, Microsoft will make available new DISM options. Microsoft has added the ablility to handle *.ffu files and multi-volume images, with a similar option being available for Windows Phone.

pattern and location of split files.
