I've got a backup of my VM's old VMWare folder including the VMDK files. It looks like VirtualBox should be able to handle VMDKs, but it's telling me it can't. Googling about it everything just talks about one VMDK file, but I've actually got 3 and suspect that may be the issue. This VM just had a single drive, yet I've got "computer_2.vmdk" (only 1 KB), "computer_2-ctk.vmdk" (8MB), and "computer_2-flat.vmdk" which is the full 250GB that my VM takes.
Is there something special I need to do to consolidate or prep these VMDKs for VirtualBox usage?
