File receiving and making-up method

The present invention discloses a file receiving and making-up method. The method comprises receiving file data of an original file from a file source by adopting a first receiving approach; judging completeness of the received original file, calculating and analyzing missing file data in the original file when data missing occurs in the original file, and making up the missing file data from the file source by adopting a second receiving approach; and inserting the make-up file data into accurate positions in the original file, thus to complete full reception of the original file. According to the file receiving and making-up method provided by the present invention, the missing file data in the original file is calculated and analyzed and then is made up from the file source by adopting the second receiving approach, thereby ensuring completeness of the original file. File reception incompleteness caused by link problems or file server faults during conventional file reception is avoided.
