This property is used to specify the type of VHD file that is specified in the VHDCreateFileName property and can be one of the following VHD file types:

·     Fixed VHD file. For this VHD type, the size of the VHD specified at creation is allocated and does not change automatically after creation. For example, if you create a 24-gigabyte (GB) fixed VHD file, the file will be approximately 24 GB in size (with some space used for the internal VHD structure) regardless of how much information is stored in the VHD file.

·     Dynamically expanding VHD file. For this VHD type, only a small percentage of the size of the VHD specified at creation time is allocated. Then, the VHD file continues to grow as more and more information is stored in it. However, the VHD file cannot grow beyond the size specified at creation. For example, if you create a 24 GB dynamically expanding VHD, it will be small at creation. However, as information is stored in the VHD file, the file will continue to grow but never exceed the maximum size of 24 GB.

This property is only valid for the MDT New Computer deployment scenario.

Note   The maximum size of the VHD file is specified in the VHDCreateSizeMax property.

This property is commonly set using a task sequence step created using the Create Virtual Hard Disk (VHD) task sequence type. You can override the value that the Create Virtual Hard Disk (VHD) task sequence step sets by configuring this property in CustomSettings.ini.

Note   To configure this property in CustomSettings.ini, you must add this property to the Properties line in CustomSettings.ini.
