For example, step 2a of the ® 2 shows that the terminal devices A, B, C = are connected to each other by wireless communication (by the virtual η shown in step 2a of FIG. 2, Γ wireless communication connection)' and start Co-editing the files. In this: terminal devices A, Β, C, and D are connected to each other by wireless communication =, device A wireless communication to terminal device B, terminal device B to terminal device C, and terminal device C communication communication The line is not ^^ ^ wireless communication connection mode, but the wireless line of the present invention is arbitrarily connected to the two 2B, C and D, respectively, two-way wireless connection - for the main two: terminal devices A, B, C Connect with D wirelessly. ;^ The terminal device has no terminal device. In the device I (4), even the other terminal devices and the main terminal device are connected to each other wirelessly. Line, this and the final wire set B, CM break content to the latest update = A 6, 〇: and 1) separately store the common modification in the record block in the update S (the previous embodiment step 201243619 S121). Therefore, in the latest update record 202a of the terminal device A, the record blocks 204Aa, 204Ab, 204Ac, and 204Ad respectively record the latest version numbers Al, Bl, C1, and D1. In other words, in the latest update record of the terminal devices a, B, C, and D, the recording blocks 204Aa, 204Ba, 204Ca, and 204Da corresponding to the terminal device a are recorded while the terminal device A is disconnected, and the recording terminal device A edits the file. The latest version number generated is A1. In the latest update record of the terminal devices A, B, C, and D, the record fields 2〇4Ab, 204Bb, 204Cb, and 204Db corresponding to the terminal device B are recorded while the terminal device A is disconnected, and the recording device device B records the file. The latest version number is B1. In the latest update record of the terminal devices A, B, C, and D, the record blocks 204Ac, 2〇4Bc, 204Cc, and 204Dc corresponding to the terminal device c are generated while the terminal device A is disconnected, and the recording device device c edits the file. The latest version number is C1. The latest update record of the terminal devices A, B, C, and D 'corresponds to the recording booths 204Ad, 204Bd, 204Cd, and 204Dd of the terminal device D while the terminal device A is disconnected, and the latest is generated by the recording terminal device D (4). The version number is the same as that of the terminal device A _ face stored in the record pad of the latest update record, so the record saves in the latest update record of all terminal devices, C and D are the same modified content. Same to each other. To be more explicit, the latest version of the new version of the record, the serial number of the record of the interception record, A B1, C1 ang D1\t, the most: the modified content of the case is the same. In other words: in the absence of ... the final knowledge, at least one of them - the same 15 201243619 disconnected from other terminal devices, all terminal devices in addition to updating the latest version number in the record block, also store the latest version number respectively Corresponding latest file modification content (that is, jointly modified content). Then, in step 2b, after the terminal device a is disconnected, the terminal devices B, c, and D that maintain the wireless connection state continue to jointly edit (co-modify) the file to the terminal device b, C in step 2C. And D are disconnected from each other 'at the same time', all terminal devices B, c and D respectively store the common modified content to the corresponding corresponding record fields in the latest update record, and respectively update the recorded latest version number B2, C2 And D2 (step S121 of the foregoing embodiment). The same as the situation when the terminal device A is disconnected in the foregoing step 2b 'because the common modification content stored in the record field in the latest update record is generated before the terminal device B, C and D are disconnected', so at all The common modification contents stored in the sever recording blocks in the latest update record in the terminal devices B, c, and D are identical to each other. That is, the latest version numbers B2, C2 recorded in the record fields in the latest update records (2〇2b, 202c, and 202d) and the latest file modification contents respectively corresponding to each other are identical to each other. Then, in step 2d, the terminal devices a and B are wirelessly connected, and the terminal devices C and D are wirelessly connected (step S101 of the foregoing embodiment). When the terminal device 8 is wirelessly connected to b (e.g., Bluetooth pairing), the terminal devices A and B each perform a version check (step sl〇5 in the foregoing embodiment). That is, the latest version number recorded in the record field 2〇4Aa corresponding to the terminal device A in the latest update record 2〇2a in the terminal device a is A1 'This is the terminal update in the latest update record 202b in the terminal device B. 5 16 201243619 The latest version number A1 recorded in the record block 2〇4Ba corresponding to A is the same, indicating that the record fields 2〇4Aa corresponding to the terminal device A are synchronized with the latest file modification contents recorded in 204Ba. Therefore, according to the foregoing embodiment (step sill in Fig. 1A and step S5 〇 5 in Fig. 1B), in the step of data synchronization, the same latest version number is not changed. For the record intercepts 204Ab and 204Bb respectively corresponding to the latest update records 2〇2a and 202b of the terminal device B, the latest update record of the terminal device B is found via the version check, and the record block 2〇4Bb recorded by the latest update record 2〇2bxin is recorded. The latest version number is B2, which is different from the latest version number B1 recorded by the recording block 2〇4Ab corresponding to the terminal device B in the latest update s recorded 202a in the terminal device A, and indicates that the terminal device b is in the latest update. The latest file modification content recorded by the record block 2〇4Ab corresponding to the record 202a is not synchronized with the latest file modification content recorded in the record field 204Bb. Moreover, the latest version numbers B1 and B2 recorded from the record fields 2〇4Ab and 204Bb respectively can find the latest version number B2 recorded by the record block 204Bb corresponding to the latest update record 202b of the terminal device b, which is newer than the latest version. The latest version number B1 recorded by the recording unit 204Ab corresponding to the terminal device B in the update record 202a is also updated. Therefore, when data synchronization is performed after the version check, according to the foregoing embodiment (step S511 of FIG. 1B) 'the latest file modification content recorded in the record block 204Bb corresponding to the terminal device B in its latest update record 2〇2b. And synchronized to the recording block 204Ab corresponding to the terminal device b in the latest update record 202a of the terminal device A, and updating the latest version number in the recording booth 204Ab of the corresponding terminal device b to be the same as the most 17 of the terminal device b. 201243619 The new update record 2G2b t, the latest version number recorded by the record block 2〇4Bb corresponding to the terminal device B, that is, the latest version number in the record is updated from B1 to B2. Further, it is to be noted that, for the terminal devices 8 and 5, the terminal devices c and D which are not connected to the terminal devices A and B via the wireless communication are regarded as disconnection terminal devices, respectively. However, it can be seen from step 2c that the latest slot modification content recorded in the record blocks 204Bc and 204Bd corresponding to the disconnection terminal devices C and D in the latest update record 202b of the terminal device B is the same as the terminal device. The most difficult case modification content in the record block Bb corresponding to B. That is, the latest file modification content corresponding to the latest version serial number is the same as the latest file modification content corresponding to the version numbers C2 and D2. Therefore, the latest slot modification content in the recording slot 204Bb corresponding to the terminal device (4) is synchronized to the recording block 2〇4Ab corresponding to the terminal device B in the terminal device a, and simultaneously synchronized to the terminal device A interrupt line. The terminal devices c and the corresponding recording bits 204Ac and 204Ad, and the terminal devices A interrupt the line terminal devices c and D corresponding recording fields 204Ac and 2〇4Ad recorded the latest version ^ by C1 and D1 Updated to C2 and D2. On the other hand, when the terminal device C is connected to the D, after the version check (step 105) of the foregoing embodiment, it is found that the latest version number recorded by the recording device corresponding to the same terminal device in the terminal devices c and D They are identical to each other, so as described in the foregoing embodiment (step S5〇5), when data synchronization is performed, it is not necessary to change the latest version number recorded by the recording block. Next, in step 2d, the connected terminal devices A and B, and the connection

The terminal devices C and D of S 18 201243619 each have a total of (four) rows of observations ((4) modifications) and jointly produce the common modification content. After the step 2e, the terminal device a is disconnected from the disk B, and the terminal devices C and D are disconnected from each other. At the same time, the terminal device A and the B share the terminal device A and the B scale are modified to modify the standard. The content to the latest update record 2〇2a and 2〇2b respectively correspond to the record block 2〇4Aa and 2_a′ and the record position Ab and 20, and update the recorded latest version number A2盥B3 respectively (the aforementioned Step S121 of the embodiment is wide, and the terminal devices c and d respectively store the common modification content of the view when the terminal device C and the D wireless connection are connected to the corresponding record seats 204Cc and 204Dc in the latest update records 202c and 202d, respectively. Recording fields 2〇4Cd and 2〇4Μ and updating the latest version number recorded as C3 肖D3 (step S121 of the foregoing embodiment) respectively. The same as the situation when the above-mentioned step 2b towel terminal device A is disconnected, due to this The common modification content stored in the record field in the latest update record is generated before the terminal devices A and B and the terminal devices c and D are disconnected from each other, and thus the record block in the latest update record in the terminal devices A and B is generated. Bit in The stored common modified contents are identical to each other. That is, the latest file modification contents respectively corresponding to the latest version numbers A2 and B3 recorded in the record blocks in the latest update records (202a and 202b) are identical to each other. The same terminal device C and The common modification contents stored in the record field in the latest update record in D are identical to each other, that is, the latest version numbers C3 and D3 respectively recorded in the record fields in the latest update records (202c and 202d) respectively. The file modification contents are identical to each other. Thereafter, in step 2f, the terminal devices B and c are wirelessly connected (step S101 of the embodiment of the previous 201243619). As in step 2d, the terminal device B is wirelessly connected to the C (for example, Bluetooth). When pairing), the terminal devices B and c each perform a version check (step S105 in the foregoing embodiment), so the latest update record in the terminal device B records the latest record recorded by the touch record place 204Bb of the 2G2b towel. The version number is B3, which is different from the latest version number B2 recorded by the record block 2〇4Cb corresponding to the terminal device B in the latest update record 202c in the terminal device c. And indicates that the latest file modification content recorded by the terminal device B in the record field 2〇4Bb corresponding to the latest update s record 202b is the latest recorded in the record field 204Cb corresponding to the latest update record 2〇2c. The file modification contents are not synchronized. And the latest version numbers B3 and B2 recorded from the record blocks 204Bb and 204Cb respectively can be recorded in the record block 204Bb corresponding to the latest update record 2〇2b of the terminal device B. The latest version number B3, / is updated more than the record field 2〇4 (^ the latest version number B2 recorded by the terminal device B in the latest update record 202c). Therefore, when data synchronization is performed after the version check, according to the foregoing embodiment (step S5ii of FIG. 1B), the latest file modification content recorded by the terminal device B in the record job 204Bb corresponding to the latest update record wipe is synchronized. The latest update record to the terminal device C is recorded in the record bit 204Cb corresponding to the terminal device b in 2G2e, and the latest version number in the record field 2〇4 (:b) of the corresponding terminal device B is updated to be the same as the terminal device B.
