The Guest Control File Manager is a feature of the Guest Additions that enables easy copying and moving of files between a guest and the host system. Other file management operations provide support to create new folders and to rename or delete files.
This feature is useful when the VM window of a guest is not visible. For example, when the guest is running in headless mode.
To use the Guest Control File Manager, the guest must be running. For powered-off guests, it is disabled automatically.
The Guest Control File Manager works by mounting the host file system. Guest users must authenticate and create a guest session before they can transfer files.
