[Solved] Resize VDI (VBoxManage)

[gibra]

I tried to expand a dynamics VDI file of 32GB size to 64GB using VBoxManage command-line. This are my steps :
1) Open Prompt Dos session (with run as administrator)
2) Navigate to C:\Program Files\Oracle\VirtualBox folder (I use latest VirtualBox 5.1.26 version)
3) launch VBoxManage with this statement:

Code: Select all

C:\Program Files\Oracle\VirtualBox>vboxmanage modifymedium "C:\VirtualBox VMs\Windows 10-1703-en\Windows 10-1703-en.vdi" --resize 64

But I receive this error:

Code: Select all

0%...
Progress state: VBOX_E_NOT_SUPPORTED
VBoxManage.exe: error: Resize medium operation for this format is not implemented yet!

The help file, on the the [--resize x] option says:
This currently works only for VDI and VHD formats, and only for the dynamically allocated variants, and can only be used to expand (not shrink) the capacity.

Then, why I get this error?
How to expand my VDI?

Thank!

a dynamics VDI file of 32GB size to 64GB

Usage:

VBoxManage modifymedium     [disk|dvd|floppy] <uuid|filename>
                            [--type normal|writethrough|immutable|shareable|
                                    readonly|multiattach]
                            [--autoreset on|off]
                            [--property <name=[value]>]
                            [--compact]
                            [--resize <megabytes>|--resizebyte <bytes>]
                            [--move <path>]

You're using the wrong number. Try with 65536.
