METHOD, DEVICE AND SYSTEM FOR TRANSFERRING AND CHECKING DATA FILES

摘要

The present invention discloses a method, device and system for transferring and checking data files. The main content includes: with the present invention, after dividing a data file into multiple data segments and calculating the respective Cyclic Redundancy Check (CRC) value for each data segment, a source device performs transmission for each data segment and the CRC value of the data segment respectively, thus enabling a target device which receives the data segments and CRC values of the data segments to check each data segment, and to promptly discover, before the data file has been transferred completely, errors which occur in the course of the data file transfer.
