Abstract: An electronic device is disclosed. The electronic device comprises a storage unit and a control unit. The storage unit stores a shared file shared by a plurality of virtual devices. If the control unit receives a request to change the shared file from a first virtual device from among the plurality of virtual devices, the control unit copies the shared file to generate a replacement file, and controls a second virtual device sought to share the shared file so as to refer to the replacement file. As such, the shared file is effectively protected, and the security of the electronic device is improved.
