Abstract: Described herein are a system and method for combining folders in a host operating system lacking a facility for performing the combining. A helper virtual machine (VM) is formed and runs a guest operating system with a facility for combining folders such as a union mount facility. The host operating system also runs a host/guest file-sharing server to share folders instead of copying them. The file-sharing server allows the VM to access host folders, perform the combination using the union mount facility, and then allows the host operating system to access the results as a shared union mount folder in the host. Any changes to the shared union mount folder in the host are automatically processed by the union mount facility in the VM and then reflected to a folder in the host operating system.
