Is deleted from the priority file selection table 207, thereby increasing the free space of the mobile-side recording unit 202 and shifting to S21. For example, when the file priority 307 of the received character data is 1, a file whose file priority 307 in the priority file selection table 207 is 3 is first searched and deleted. Also, the priority file selection table 20
If there is no file with the file priority 307 of 3 in the file 7, the file with the file priority 307 of 2 is searched and deleted. Further, when there is no file whose file priority 307 is 2 in the priority file selection table 207, the file whose file priority 307 is 1 is searched and deleted.

If the file priority 307 of the received transfer data is 2, the priority file selection table 2
A file is searched for the file priority level 307 of 07 in the order of 3 and 2, and the corresponding file is deleted. If the file priority 307 of the received character data is 3,
File priority 3 in priority file selection table 207
07 searches the file of 3 and deletes the file. Next, in S23, the file name 30 is stored in the directory corresponding to the file type 302 of the portable recording unit 202.
5 and the file name 3 in which the data content 306 is registered
Then, recording is performed in the recording area allocated to 05, and the process proceeds to S24. In S24, the file name 3 recorded in the corresponding file type 302 of the priority file selection table 207 is stored.
05 and the file priority 307 are registered, and the process is terminated.

Thus, even if the free space in the portable recording unit 202 is small, the file with a low priority is deleted to increase the free space in the portable recording unit 202, and the receiving terminal 100
Since the transfer data received from “a” is recorded, the received transfer data can be reliably recorded in the portable recording unit 202.
In the above description, if the file priorities 307 are the same, the transfer data received from the receiving terminal 100a is prioritized, the existing file is deleted in the portable recording unit 202, and the received character data is transferred to the portable recording unit. 202, the priority of the received transfer data and the portable recording unit 20
The weight of the priority of the existing file 2 may be set in any manner according to the preference of the distribution source and the user. In this embodiment, the file priority 307 is set.
