This kind of issue can be solved in VMware easily if you've installed the vmware-tools.
I am newbie to VirtualBox. I wonder if the VirtualBox Guest Additions have a similar function script or not?

Hello Flavio, Yes, this is because when the guest writes to the disk and then frees that space, VirtualBox has no way of knowing that it has been freed, so it does not remove it from the file. The only space that VirtualBox really knows is free on the disk is space that has never been written to (or if I recall correctly blocks filled with zeros).
