The invention discloses a recombining method and device for a transplantable executive file. The method comprises the following steps: reading a functional logic sequence in an original transplantable executive file; obtaining an invoking record of the functional logic sequence; generating a ranking position by adopting the invoking record; and recombining the functional logic sequence according to the ranking position to obtain the target transplantable executive file. According to the method and the device, the invoking record of the functional logic position of the transplantable executive file is obtained to generate the ranking position, and then the functional logic position is recombined according to the ranking position, so that a CPU (Central Processing Unit) can directly read the functional logic position in memory to avoid the frequent reading of a disk by the CPU, reduce the consumption of system resources and reduce the generation of missing page interruption, so that the cold start speed of application programs is increased.
