Abstract
Embodiments of the present invention provide a file transfer method. A file is received and cached from a sending device. At least one data packet is sent to a receiving device at a preset interval to maintain a data connection between the sending device and the receiving device. The file is detected after the file is cached to determine whether the file has a security risk. The cached file is sent to the receiving device if the file has no security risk.
