Increase size of virtual disk
Use the command 'VBoxManage' as this must be done from the console (MS-DOS prompt). For Windows XP the VBoxManage is not in the path by default, and the default base directory is Program Files. The space causes an error. To avoid, the following example is provided for Windows XP users:
C:\Progra~1\Oracle\VirtualBox\VBoxManage modifyhd "Win XP SP3 Image.vdi" --resize 45888
Here the VBoxManage command is used to resize a 10GB image to 45GB. The quotes around the image name prevent an error due to the spaces. The use of the 8 char substitute Progra~1 prevents an error.
