Abstract: A system for file sharing includes a file integration service program and a dongle device. The file integration service program is installed in a first electrical device and provides to-be-shared files accessible by the first electrical device. The dongle device includes a hot-plug port, a microcontroller and a wireless communication module. The hot-plug port is for coupling to a second electrical device. When the hot-plug port is coupled to the second electrical device, the microcontroller disassembles and packages a first instruction with a SCSI standard from the second electrical device into the first instruction with a wireless communication standard. The wireless communication module transmits the first instruction with the wireless communication standard to the first electrical device, so that the second electrical device can access the to-be-shared files via the dongle device.
