About VHD & VHDX

VHD, the short of Virtual Hard Disk, is a file format which represents a virtual hard disk drive. If you create Windows image backup using Backup and Restore, you now get Windows backup to VHD and you will get a WindowsImageBackup folder in the destination, and the path just like:\WindowsImageBackup\computer name\Backup YYYY-MM-DD HHMMSS. And get multiple .VHD files and several .xml files. How many VHD files mean that you have how many disks or partitions.

VHDX (Virtual Hard Disk V2) is the successor format to VHD. Now it is used for disk images instead of VHD. Because there are some difference between VHD and VHDX: capacity limit. VHD is limited up to 2 TB while the VHDX is limited up to 64 TB. You can mount VHDX just like mount VHD.
