The invention relates to a lose-tolerable file transfer control method applicable to a space communication system, comprising the following steps: 1) data knitting process: (1.1) selecting a step d; (1.2) selecting d data blocks randomly from N original data blocks and recording as S'1, S'2,..., S'd; (1.3) carrying out bitwise XOR operation on the d data blocks; 2) data unknitting process: (2.1) finding a data block with step d=1, receiving more data if the received data blocks have no data block with d=1, till receiving the data block with d=1; (2.2) restoring Sk, and leading to Sk=tn; (2.3)finding other received and Sk-related data blocks ti (i is not equal to n) according to a generated matrix; (2.4) deleting all 'edges' connected with Sk; (2.5) if all Sies are restored, obtaining an original file; and otherwise back to step (2.1). The lose-tolerable file transfer control method can effectively avoid packet loss of link, has strong transmission reliability, shortens the time delayof file transfer, and increases throughput.
