VBoxManage extpack

The "extpack" command allows you to add or remove VirtualBox extension packs, as described in "Installing VirtualBox and extension packs".

• To add a new extension pack, use VBoxManage extpack install <.vbox-extpack>. This command will fail if an older version of the same extension pack is already installed. The optional --replace parameter can be used to uninstall the old package before the new package is installed.
• To remove a previously installed extension pack, use VBoxManage extpack uninstall <name>. You can use VBoxManage list extpacks to show the names of the extension packs which are currently installed; please see "VBoxManage list" also. The optional --force parameter can be used to override the refusal of an extension pack to be uninstalled.
• The VBoxManage extpack cleanup command can be used to remove temporary files and directories that may have been left behind if a previous install or uninstall command failed.

The following commands show examples how to list extension packs and remove one:
