File sharing method and apparatus thereof

An embodiment of the invention discloses a file sharing method and an apparatus thereof. The file sharing method applied to a sending terminal comprises the following steps of sharing a chained address of a file and receiving a verification request sent by a receiving terminal according to the chained address, wherein the verification request carries information of the file to be opened; according to the verification request, determining an authority of the receiving terminal to open the file; and when the receiving terminal possesses the authority to open the file, sending agreed open information to the receiving terminal so that the receiving terminal opens the file. In the embodiment of the invention, the receiving terminal can successfully open the file when the sending terminal confirms that the receiving terminal possesses the authority of opening the file. Therefore, only an object which is trusted by the receiving terminal can successfully open the file so that file sharing safety is greatly increased
