Guest Additions offer the following features

2. Shared folders : Easy to share files between host and guest machine just like you do in Windows network share.VirtualBox treat a certain host directory as a shared folder, and VirtualBox will make it available to the guest operating system as a network share.

3. Better video support : Custome video drivers shipped with VirtualBox Guest Additions provides extra high and non-standard video modes as well as accelerated video performance. With Guest Additions,3D graphics and 2D video for guest applications can be accelerated.
