Virtualbox - How to extract files from a `.vdi` file

To extract files from a .vdi (Virtual Disk Image) file, you typically need to mount it as a virtual disk and then access its contents like a regular disk. Here's a step-by-step guide on how to achieve this:

Using VirtualBox

If you have VirtualBox installed and the .vdi file belongs to a Virtual Machine (VM), you can mount the .vdi file as a virtual disk and access its contents from your host operating system.

  1. Open VirtualBox:

    • Start VirtualBox, but do not start the virtual machine associated with the .vdi file.

  2. Add the .vdi File:

    • Go to File -> Virtual Media Manager.
    • Click on Add to add the .vdi file to VirtualBox.

  3. Create a New Virtual Machine (if necessary):

    • If the .vdi file is not associated with an existing VM, you can create a new VM and attach the .vdi file as its virtual disk.

  4. Mount the Virtual Disk:

    • Start the VM (or use an existing one) that has the .vdi file attached.
    • Once the VM is running, you can access the virtual disk contents just like you would with any physical disk.

  5. Access Files:

    • Inside the running VM, you can copy or extract files from the virtual disk to another location within the VM.
    • Alternatively, if you want to access these files from your host operating system, you can set up shared folders between the VM and the host.

Using VBoxManage Command Line

If you prefer using the command line, VirtualBox provides VBoxManage utility to manage virtual machines and disk images.

  1. List Virtual Media:

    • Open a terminal or command prompt.

    • Navigate to the VirtualBox installation directory or ensure VBoxManage is in your system's PATH.

    • Use the following command to list the virtual media (including .vdi files):

      VBoxManage list hdds

  2. Extract Files from .vdi:

    • You can mount the .vdi file using VBoxManage or other tools and then access its contents. For example:

      VBoxManage internalcommands createrawvmdk -filename /path/to/new.vmdk -rawdisk /path/to/your.vdi

      This command creates a new virtual disk (new.vmdk) that is linked to the raw disk (your.vdi).

Using Third-Party Tools

If you're looking to directly extract files from a .vdi file without VirtualBox, there are third-party tools available that can mount .vdi files as drives on your operating system. Examples include:

  • Virtual Disk Development Kit (VDDK): VMware's toolset for manipulating virtual disk files, which includes support for .vdi.
  • Mounting Tools: Tools like vdiskmanager for VMware or disk imaging tools that support .vdi format.

Important Considerations

  • Backup: Always back up your .vdi file before attempting any extraction or manipulation.
  • Permissions: Ensure you have appropriate permissions to access and manipulate the .vdi file and its contents.
  • Virtual Machine State: If the .vdi is associated with a running VM, consider shutting down the VM properly before attempting to access its disk image to prevent data corruption.

By following these steps, you should be able to extract files from a .vdi file using VirtualBox or other compatible tools effectively. Adjust the specific commands and steps based on your operating system and tools available.
