PURPOSE: A method for loading an execution file in an exchange is provided to partially load an execution file by requesting data transmission at a uniform size using the data location and size of file header information. CONSTITUTION: If a receiving unit receives a header information request message for an execution file(S10), a transmitting unit transmits the header information of the execution file to the receiving unit(S12). The transmitting unit judges whether a data transmission request is generated from the receiving unit within a preset time(S14). In case that the data transmission request is transmitted with a desired data size and an offset indicating the location of desired data, the transmitting unit finds out the location of the data, divides the data by the requested size, transmits the data to the receiving unit with the offset indicating the location of the data(S16). After transmitting the last data of the requested data(S18), the transmitting unit transmits a check sum to the receiving unit(S20) and judges whether a data end message indicating that the receiving unit has received all the data normally is received(S22). If the data end message is received, the transmitting unit judges whether a loading end message is received(S24).
