In the case of =: r, the two discs are shown in the figure. In the first figure, the user first walks with the computer = and the computer 11 is stalked. At this time, the memory 13 is stored with the entire contents, and the contents of the folder 'follow the flash drive 13 and the computer 12 are executed. The portable computer and the computer will be used to complete the synchronization between the folders of the computer 11 and 12. The above has many shortcomings. First, if the information is cool: the size of the flash drive 13 needs to be large. Secondly, if you can't find or lose the light U, you need to find another one: 'Copy all the folders again, if the contents of the folder' will take a lot of time; Finally, if you use _With multiple flash drives, you must remember which flash drive is used for data synchronization and increase the inconvenience of use. 4 201020820 [Invention] In view of the present invention, the object is to provide data synchronization. System and method 'which can improve the synchronization speed and ease of use, and save the storage space of the intermediary storage device. ❺ ❹ #发明揭露- Kind of data synchronization system, comprising: a first electronic device 'storage has a first capital Lost, and maintain the first-folder-first-file list to record the first folder's broadcast update information; - the second electronic display, store a second folder, and maintain the second data a second broadcast list for recording the second information update schedule information; and an intermediary storage device; wherein, when the first folder and the second folder are synchronized with the Nth time The first electronic device and the second electronic device respectively save and synchronize the first file table and the second file table after synchronization, wherein N is a positive integer, the first file table and the second file of the backup The schedule remains unchanged until the N+1th synchronization of the first folder and the second folder is performed, wherein the first folder and the second data are synchronized to the N+1th synchronization When executed, the first electronic device copies the backup-file list of the backup to the intermediary storage device to generate a third file table, and then compares the third file table with the current first broadcast table. To find that the first-folder order needs to be updated to the mediation storage device to the ^-file And copying the first slot to the intermediate storage device and correspondingly updating the third slot table; then the second electronic display is compared to the third file list and the current second slot table, In order to find that the intermediate storage device needs to be updated to at least one second standard of the second data folder, and then copy the second file from the intermediary storage device or 201020820 to the second data folder and update correspondingly The second file table. The invention further discloses a data synchronization method for synchronizing the content of the first data folder of one of the first electronic devices and the second data center of one of the second electronic devices. The method includes: maintaining a first file table of one of the first folders and a second slot table of the second folder, wherein the first file table and the second file table respectively record the first folder and the first file The file update information of the second folder; and when the second folder of the first folder and the second folder are synchronized, respectively, the synchronized first file table and the second file table are separately saved as a backup , where N is a positive The first file table and the second file table of the backup remain unchanged until the first N+1 synchronization of the first folder and the second folder is performed; the first folder and the first folder are The N+1th synchronization of the second folder includes the following steps: (magic copying the first file table of the backup to an intermediary storage device to generate a second file table; (b) comparing the third file file And the current first file list to find at least one first file in the first folder to be updated to the media storage device; (c) copying the first file from the first folder to the Intermediary storage device, and correspondingly updating the third file list; (d) comparing the third file table with the current second file table to find that at least the intermediate storage device needs to be updated to the second data folder And a second file; and (e) copying or moving the second file from the media storage device to the second folder, and correspondingly updating the second file table. [Embodiment] FIG. 2 is a block diagram of an embodiment of a data synchronization system 20 of the present invention, which includes a first electronic device 21, a second electronic device 22, and an intermediate storage device 23. The first electronic device 21 stores a first folder 211 and maintains a first file table 212' corresponding to the first folder 211 to record the file included in the first folder 211 and related file update information. The second electronic device 22 stores a second folder 221 and maintains a second file table 222 corresponding to the second folder 221 to record the file included in the second folder 221 and related file update information. As long as there is any update to the file in the first folder 211 (or the second folder 221), it will be correspondingly recorded in the file update information of the first file table 212 (or the second file table 222). When the first electronic device 21 and the second electronic device 22 are disconnected for communication, the data synchronization system 20 can use the intermediate storage device 23 as the transmission medium to the contents of the first folder 211 and the second folder 21 Perform synchronization. However, whether the connection between the first electronic device 21 and the first electronic device 22 does not affect the implementation of the present invention does not limit the scope of the patent of the present invention. The first electronic device =, the second electronic device 22 can be a personal computer, and the intermediate storage device can be a flash drive, a memory card or an external hard disk. First, whether the first folder 211 and the second folder 221 are
次執行同步化，資料同步系統20的同步過程也不 太相回 m I 步系 因此，以下分成兩種情形，分另1J詳述資料同 、繞20如何執行第一資料失211與第二資料夾π 的同步化： 7 201020820 次執f 211與第二資料夹-間係第 ρβ^ 先’第一資料夾211與中介儲存裝置23 執打同步化：由於第一資料夾211與第二資料夾221 曾執行過同步化，第—電子裝置21需將第一資 寻夹211之全部内容及第一槽案表212複製至中介儲 ，置23，以產生一第三槽案表(在本發明令，於進行 同步化時所複製至中介儲存裝置23Synchronization is performed once, and the synchronization process of the data synchronization system 20 is not quite related to the m I step system. Therefore, the following is divided into two cases, and the details of the data are the same as that of the second data. Synchronization of the clip π: 7 201020820 The second file f 211 and the second folder - the first ρβ ^ first 'the first folder 211 and the intermediate storage device 23 to perform synchronization: due to the first folder 211 and the second data The folder 221 has been synchronized, and the first electronic device 21 needs to copy the entire contents of the first search folder 211 and the first slot table 212 to the intermediate storage, and set 23 to generate a third slot table (in this case). The invention is copied to the intermediate storage device 23 during synchronization
為第三槽案表，圖中並未顯示)。因此，此 表係與第-槽案表212同步，且中介儲存裝置23健存 了第一資料夾211之全部内容。另外，第一電子裝置 21還將第-檔案表212另存以作為備份。 (1-2)接著，中介儲存裝置23與第二資料夾η 間執行同步化··第二電子裝置22比對第三槽案表與目 前之第二檔案表222,以發現中介储存裝置Μ中需更 新至第二資料夾221之至少一播案(為便於行文，下文 稱為第二檔案)或者發現第二資料夾221中需更新至中 介儲存裝置23之至少—職(下文稱為第三檔案），亦 即’該第二檔案是中介儲存褒置23有而第二資料夾 221沒有的檔案，或者是中介儲存裝置幻與第二資料 夾221皆有，但中介儲存裝置23中的第二檔案比第二 資料夹221中的還新；而該第三檔案是第二資料夾 221有而中介儲存裝置23沒有的檔案，或者是中介儲 存裝置23與第二資料夾221皆有，但第二資料夾221 中的第三檔案比中介儲存裝置23中的還新。 201020820 若前述比對結果未發現任何第二檔案或第三襠 案，則表示第三檔案表(此時代表第一資料夾211的内 容)與目前之第二檔案表222(其代表第二資料夾221的 内容）同步，因此不需進行第一資料夾211與第二資料 夾221之同步化；若比對結果發現有第二檔案，則第 二電子裝置22將所發現之第二檔案從中介儲存裝置 23移動(或複製)至第二資料夹221，並對應地更新第 二播案表222;若比對結果發現有第三檔案，則第二 〇 電子裝置22將所發現之第三檔案從第二資料夾221複 製至中介儲存裝置23，並對應地更新第三檔案表。執 行完所有第二檔案與第三檔案的更新後，可使第二檔 案表222與第三檔案表同步，接著，第二電子裝置22 將同步後之第二檔案表222另存，以作為備份之第二 檔案表(若是先前已有備份之第二檔案表，則是將該備 份之第二檔案表更新為同步後之第二檔案表222)。 請注意’若前述比對結果僅發現有第二檔案而未 ❹ 發現第三檔案，則表示第二資料夾221中未有需更新 至第一資料夾211的檔案，因此在第二電子裝置22將 所發現之第二檔案更新至第二資料夾221後，即已完 成第一資料夾211與第二資料夹221之同步化；而若 比對結果發現有第三檔案，則不論有無發現第二檔 案，皆需進行以下之(1-3)，以將所發現之第三檔案更 新至第一資料夾211。 請注意，當第二電子裝置22將第二檔案從中介儲 存裝置23移動至第二資料夾221時，雖然此時第二播 201020820 案係從中介儲存裝置23被刪除，但中介儲存裝置23 中之第二檔案表並不做對應的變動，以使第三檔案表 能與第二資料失221之第二檔案表222保持同步。 G-3)最後，中介儲存裝置23與第一資料夾211 間再執行同步化：第一電子裝置21比對第三檔案表與 目前之第一檔案表212，以發現中介儲存裝置23中需 更新至第一資料夾211之至少-播案(下文稱為第四檔 案’亦即前述(1-2)中存於中介儲存裝置23之第三檔 案）’再將該第四檔案從中介儲存裝置23複製或移動 至第一資料夾211，並對應地更新第一檔案表212，使 第一檔案表212可與第三檔案表同步(亦即，可與第二 檔案表222同步），接著，第一電子裝置21將先前所 備份之第一檔案表更新為同步後之第一檔案表212。 至此，第一資料夾211與第二資料夾221之同步化即 办Λ、 7L 成0 請注意’前述(1-3)係假設第一資料夾211之檔案 在前述(1·1)執行後未做更新。若已做過更新，則（1_3) 除了執行前述將第四檔案更新至第一資料夾211的動 作外，亦須將第一資料夾211中已做過更新的槽案更 新至中介儲存裝置23，並對應地更新第三檔案表，接 著再跳回(1-2)重新執行，如此反覆執行(1-2)與(1_3)直 至第一檔案表212與第二檔案表222同步為止。 在第一檔案表212與第二檔案表222達成同步之 後’前述所備份之第一檔案表與第二檔案表在下一次 執行第一資料夾211與第二資料夾221間之同步化前 201020820 將保持不變(後文會再詳述原因）。 (2)第一資料夹211與第二資料央221間係第N 次執行同步化，其t N大於一： (2_1)首先’第一資料夾21】與令介儲存裝置23 間執行同步化：由於第一資料夾211與第二資料夾221 曾執行過同步化，所以第一電子裝置21與第二電子裝 置22分別存有前一次同步化完成時所備份之第一檔 案表與第二檔案表。第一電子裝置21將該備份之第一 檔案表複製至中介儲存裝置23，以作為第三檔案表， 接著比對目前之第一檔案表212與該第三檔案表，以 發現目前之第一資料夾211 _需更新至中介儲存裝置 23之至少一檔案(下文稱為第一檔案乂，再將該第一檔 案複製至中介儲存裝置23,並對應地更新第三槽案 表，以使第三檔案表與第一檔案表212同步。 ' 由於第三檔案表為前一次同步化完成時所備份之 第一檔案表，其代表前一次同步化完成之時第一資料 夾211的播案更新狀態，因此由前述第一槽案表Μ〗 與第三檔案表的比對結果，即可知第一資料夾211從 前一次同步化完成後更新了哪些檔案，而因為前一次 同步化完成後，第一資料夾211與第二資料夾221具 有相同的内容，因此只需將第一資料夾211從前一次 同步化完成後有更新的檔案複製至中介儲存裝置23 即可，而不需將所有第-資料夾211的内容皆複製至 中介儲存裝置23。如此，可節省同步化執行所需之時 間與儲存空間。 201020820 此外’也由於第一電子裝置21與第二電子裝置 22分别保留了前一次同步化時所備份之第一檔案表與 第二檔案表，中介儲存裝置23亦可替換為任何其他未 曾參與執行第一資料夾211與第二資料夾221之同步 化的儲存裝置，以使資料同步系統2〇在運作上更具彈 性。換s之，當使用者在執行第一資料夾211與第二 資料央221之第N次同步化時(N>1)，不一定要藉由 之前同步化所使用之中介儲存裝置23,而可以選擇手 邊任何可用之隨身碟、記憶卡或外接式硬碟等儲存裝 置來進行，如此更便於同步化的執行。 (2-2)接著，中介儲存裝置23與第二資料夾221 間執行同步化：這部分與(1_2)相同，此處不再贅述。 (2-3)最後，中介儲存裝置23與第一資料夾211 間再執行同步化：這部分亦與(1-3)相同，此處不再贅 述0 前述(M)至(1-3)(或(叫至阳))的過程亦可反過 來，從第一電子裝置22開始執行，亦即，第二資料夾 221先與中介儲存裝置23間執行同步化，過程細節與 (M)(或(2-1))近似；接著’中介儲存裝置與第一資 料夾211間執行同步化，過程細節與(12)(或(2 2))近 似，最後，中介儲存裝置23與第二資料央221間再執 行同步化，過程細節與(1_3)(或(2_3))近似。 在一較佳實施例中，第一檔案表212所記錄之檔 案更新資訊包含第一資料夾211之各播案的名稱、最 近更新者與最近更新版本代碼，而第二槽案表222所 12 201020820 記錄之檔案更新資訊包含第二資料夾221之各檔案的 名稱、最近更新者與最近更新版本代碼。第3圖係以 一實例顯示第一檔案表212與第二檔案表222的内 容’其中，最近更新者為第一電子裝置21(以A代表) 或第二電子裝置22(以B代表），最近更新版本代碼為 總體(global)版本代碼，亦即，若某一檔案在某一更新 者進行更新後之版本代碼為η，則同一資料夾内由同 一更新者進行下一次檔案更新時，不論所更新之檔案 為何，更新後的檔案之版本代碼為η+1，而不同更新 者所產生之更新版本代碼則分別累計。以第3圖為 例，若第一電子裝置21對file2進行更新(亦即，更新 者為A)，則由於第一檔案表212中更新者為a之最高 版本代碼為7，所以file2之最近更新版本代碼需改為 8’最近更新者仍維持為A;若第二電子裝置22對仞斜 進行更新(亦即，更新者為B)，則由於第二檔案表222 中更新者為B之最高版本代碼為2 , fjie2之最近更新 版本代碼需改為3，最近更新者則改為b。 在前述(1-1)至(1-3)與(2-1)至(2_3)的過程中，於進 行兩個播案表間之比對時，是要找出就同—個播案而 δ ’哪個槽案表巾之槽案比較新^在此較佳實施例中， 就同-個觀而言，若兩個職表巾之最近更新者相 同’則最近更贿本代姐較高的，即為麟的播案， 例如’若比較第3圖中兩個檔案表，則可發現第一檔 案表212之腕較第二播案表222之filel為新；另 -方面，就同-個權案而言，若兩個播案表中之最近 201020820 更新者不相同，則有兩種情形： (-）可判斷何者較新：例如在第3圖中第一播 案表212之me2之最近更新者為A，而第二槽案表從 之fik2 t最近更新者為B，兩者的最近更新者不相 同。不過’由於第二標案表222中更新者為A的最高 版本為5(即制），其大於第一槽案表212中贴的 最新版本(即4)，這表示版本為4之咖f在第二播 案表222上出現過，所以，第二槽案表拉之磁比 Ο 第一襠案表212之file2為新。 (二）不能判斷何者較新：例如，若前述(一)所舉 的例子中，第二檔案表222中更新者為A的最高版本 _ 3，而小於第-檔案表212 +贴的最新版本（即 4) ’則無法判斷哪個檔案表之_比較新。此時，資 制步祕20可同時顯示兩_案表之file2，由使用 者來決定哪個比較新或者決定要保留哪一個。 請注意’第3圖所示之檔案更新資訊的格式僅為 ❹ -實施例’其他種檔案更新資訊的格式，只要能藉由 其比較兩個檔案表中之同-個槽案哪個較新，就不脫 離本發明之範圍。 在另一較佳實施例中，在執行第一資料夾211與 第二資料夾221之第一次同步化時，第一電子裝置21 會儲存一第一同步資訊’其包含第一電子裝置Μ與第 二電子裝置22之識別碼、第一資料夾211與第二資料 夾221之名稱以及一第一指標(p〇inter)，該第一指標用 以指向所備份之第一檔案表；第二電子裝置22會儲 201020820 存-第二同步資訊’其包含第—電子裝置21與第二電 子裝置22之識別碼、第一資料夾211與第二資料爽 221之名稱以及-第二指標，該第二指標用以指向所 備份之第二儲表。第1步資訊與第二同步資訊除 了分別提供第-電子裝置21與第二電子裝置22進行 管理之用’亦可用於第-資料夾211與第二資料爽221 的同步化過程。例如，麵述㈣巾1 —電子裝置 2」係第一同步資訊中之第-指標，以找到 刖一次同步化時所備份之第—财表，再將其複製至 中介儲存裝置23中。 丹册兵複策至 在前述所有實施例中，第一電子 子裝置22所執行的各個動 興弟一電 軟體來實現，料執行—資料同步 軟體來實S対_錢體謂存 21與第二電子裝置22、或是 *冤千裝置 用以自動化地執行第一資料夾2;裝置23中，可 的同步化。 #枓夾211與第二資料夾22!

However, the third file in the second folder 221 is newer than in the media storage device 23. 201020820 If the second comparison file or the third file is not found in the foregoing comparison result, it indicates that the third file table (which represents the content of the first folder 211 at this time) and the current second file table 222 (which represents the second data) The content of the folder 221 is synchronized, so that synchronization of the first folder 211 and the second folder 221 is not required; if the comparison result is found to have a second file, the second electronic device 22 will discover the second file found. The intermediate storage device 23 moves (or copies) to the second folder 221 and updates the second broadcast table 222 correspondingly; if the comparison result finds that there is a third file, the second electronic device 22 will find the third file. The file is copied from the second folder 221 to the intermediate storage device 23, and the third file table is updated correspondingly. After the update of all the second file and the third file is performed, the second file table 222 can be synchronized with the third file table, and then the second electronic device 22 saves the synchronized second file table 222 as a backup. The second file table (if the second file table has been previously backed up, the second file table of the backup is updated to the second file table 222 after synchronization). Please note that if the foregoing comparison result only finds the second file and the third file is not found, it means that there is no file in the second folder 221 that needs to be updated to the first folder 211, so the second electronic device 22 After updating the found second file to the second folder 221, the synchronization between the first folder 211 and the second folder 221 is completed; and if the comparison result is found to have a third file, the presence or absence of the discovery For the second file, the following (1-3) are required to update the found third file to the first folder 211. Please note that when the second electronic device 22 moves the second file from the intermediate storage device 23 to the second folder 221, although the second broadcast 201020820 is deleted from the intermediate storage device 23, the intermediate storage device 23 is The second file table does not make corresponding changes, so that the third file table can be synchronized with the second file table 222 of the second data loss 221 . G-3) Finally, the intermediate storage device 23 performs synchronization with the first folder 211: the first electronic device 21 compares the third file table with the current first file table 212 to find the intermediate storage device 23 Updating to at least the first folder 211 (hereinafter referred to as the fourth file 'that is, the third file stored in the intermediate storage device 23 in the foregoing (1-2)) and then storing the fourth file from the intermediary The device 23 copies or moves to the first folder 211, and correspondingly updates the first file table 212 so that the first file table 212 can be synchronized with the third file table (ie, can be synchronized with the second file table 222), and then The first electronic device 21 updates the previously archived first file table to the synchronized first file table 212. So far, the synchronization between the first folder 211 and the second folder 221 is as follows: 7L is 0. Please note that the above (1-3) assumes that the file of the first folder 211 is executed after the above (1·1) is executed. No updates have been made. If the update has been made, (1_3), in addition to performing the foregoing operation of updating the fourth file to the first folder 211, the slot file in the first folder 211 that has been updated must also be updated to the intermediate storage device 23. And correspondingly update the third file table, and then jump back (1-2) to re-execute, thus repeatedly executing (1-2) and (1_3) until the first file table 212 is synchronized with the second file table 222. After the first file table 212 and the second file table 222 are synchronized, the first file table and the second file table backed up before the next execution of the synchronization between the first folder 211 and the second folder 221 will be 201020820. Stay the same (more on this later). (2) The first data folder 211 and the second data center 221 are synchronized for the Nth time, and the t N is greater than one: (2_1) First, the synchronization between the first data folder 21 and the media storage device 23 is performed. Since the first folder 211 and the second folder 221 have been synchronized, the first electronic device 21 and the second electronic device 22 respectively store the first file table and the second file that were backed up when the previous synchronization was completed. File list. The first electronic device 21 copies the first file list of the backup to the intermediate storage device 23 as a third file table, and then compares the current first file table 212 with the third file table to find the first one. The folder 211_ needs to be updated to at least one file of the mediation storage device 23 (hereinafter referred to as the first file file, and then the first file is copied to the intermediate storage device 23, and the third slot table is updated correspondingly to enable The third file table is synchronized with the first file table 212. ' Since the third file table is the first file table that was backed up when the previous synchronization was completed, it represents the broadcast of the first folder 211 when the previous synchronization was completed. State, therefore, by comparing the foregoing first slot table 与 with the third file table, it can be known that the first folder 211 is updated after the previous synchronization is completed, and because the previous synchronization is completed, the first A folder 211 has the same content as the second folder 221, so that it is only necessary to copy the first folder 211 from the archive after the previous synchronization is completed to the intermediate storage device 23, without having to - The contents of the folder 211 are copied to the intermediate storage device 23. Thus, the time and storage space required for synchronization execution can be saved. 201020820 In addition, since the first electronic device 21 and the second electronic device 22 respectively retain the previous time When the first file table and the second file table are backed up during synchronization, the mediation storage device 23 can also be replaced with any other storage device that has not participated in the synchronization of the first folder 211 and the second folder 221 to enable the data. The synchronization system 2 is more flexible in operation. In other words, when the user performs the Nth synchronization of the first folder 211 and the second data center 221 (N>1), it is not necessary to The intermediate storage device 23 used for synchronization can be selected, and any storage device such as a flash drive, a memory card or an external hard disk can be selected at hand, which is more convenient for synchronization execution. (2-2) Next, the intermediate storage Synchronization is performed between the device 23 and the second folder 221: this portion is the same as (1_2) and will not be described here. (2-3) Finally, the mediation storage device 23 performs synchronization with the first folder 211: This part The points are also the same as (1-3), and the process of (M) to (1-3) (or (to the yang)) may be reversed from the first electronic device 22, That is, the second folder 221 is first synchronized with the intermediate storage device 23, and the process details are approximated by (M) (or (2-1)); then the 'intermediary storage device is synchronized with the first folder 211. The process details are approximated by (12) (or (2 2)). Finally, the intermediate storage device 23 and the second data center 221 are synchronized again, and the process details are approximated by (1_3) (or (2_3)). In the preferred embodiment, the file update information recorded by the first file table 212 includes the names of the first files of the first folder 211, the latest updater and the latest update version code, and the second slot table 222 is 12 201020820 records. The file update information includes the names of the files of the second folder 221, the latest updater and the latest update version code. Figure 3 shows the contents of the first file table 212 and the second file table 222 by an example, wherein the most recent updater is the first electronic device 21 (represented by A) or the second electronic device 22 (represented by B), The most recent update version code is the global version code, that is, if a version file is updated after an updater has a version code of η, then the same folder is updated by the same updater in the same folder, regardless of The updated file has a version code of η+1, and the updated version code generated by different updaters is accumulated separately. Taking FIG. 3 as an example, if the first electronic device 21 updates file2 (that is, the updater is A), since the highest version code of the updater in the first file table 212 is 7, the recent file2 is The updated version code needs to be changed to 8', the latest updater remains at A; if the second electronic device 22 updates the skew (ie, the updater is B), since the updater in the second archive table 222 is B The highest version code is 2, the most recent update code for fjie2 needs to be changed to 3, and the most recent updater is changed to b. In the process of (1-1) to (1-3) and (2-1) to (2_3), when comparing the two broadcast forms, it is to find out the same--a broadcast And δ ' which groove case towel case is relatively new ^ In this preferred embodiment, in the same view, if the two recent watches are the same as the latest update, then the recent bribe High, that is, the broadcast of Lin, for example, 'If you compare the two file tables in Figure 3, you can find that the wrist of the first file table 212 is newer than the filel of the second broadcast form 222; For the same case, if the most recent 201020820 updaters in the two broadcast schedules are different, there are two cases: (-) It can be judged which is newer: for example, in the first broadcast table 212 in FIG. The most recent update of me2 is A, and the second schedule is the latest update from fik2 t to B, the latest update of the two is not the same. However, since the highest version of the updater A in the second list 222 is 5 (that is, the system), which is larger than the latest version (ie 4) posted in the first slot table 212, this indicates that the version is 4 Appeared on the second playlist 222, so the magnetic ratio of the second slot table is new to file2 of the first file table 212. (2) It is impossible to judge which is newer: For example, in the example given in (a) above, the updater in the second file table 222 is the highest version of A_3, and is smaller than the latest version of the second file table 212+ (ie 4) 'You can't judge which file table is newer. At this point, the resource step 20 can simultaneously display the file2 of the two _ case tables, and the user decides which one is newer or decides which one to keep. Please note that the format of the file update information shown in Figure 3 is only the format of the "Others" file update information, as long as it can compare which of the two files in the two file tables is newer. Without departing from the scope of the invention. In another preferred embodiment, when the first synchronization of the first folder 211 and the second folder 221 is performed, the first electronic device 21 stores a first synchronization information that includes the first electronic device. And the identifier of the second electronic device 22, the names of the first folder 211 and the second folder 221, and a first indicator (p〇inter), the first indicator is used to point to the first file table that is backed up; The second electronic device 22 stores the 201020820 storage-second synchronization information, which includes the identification codes of the first electronic device 21 and the second electronic device 22, the names of the first data folder 211 and the second data storage 221, and the second indicator. The second indicator is used to point to the second table that is backed up. The first step information and the second synchronization information may be used for the synchronization of the first folder 211 and the second data 221, respectively, in addition to providing the first electronic device 21 and the second electronic device 22 for management. For example, the face (four) towel 1 - the electronic device 2" is the first indicator in the first synchronization information to find the first fiscal table backed up in one synchronization, and then copied to the intermediate storage device 23. In addition to all the foregoing embodiments, the first electronic sub-device 22 implements each of the dynamics of the electronic software to implement, and the implementation of the data synchronization software to implement the S対_钱体存存21 and The two electronic devices 22, or *1000 devices, are used to automatically execute the first data folder 2; in the device 23, the synchronization is possible. #枓夹211 and the second folder 22!

Recording _Step Yang includes the T column step. Step: Determine whether it is the first execution synchronization, if yes: continue to perform step 4G2, no ship to step step 402: the first content of the first data folder 211 and the first slot The table 212 is copied to the intermediary storage device 23, 2〇1〇2〇82〇 to generate a third file list, and the current first file table 212 is saved as a backup. Then, go to step 407. Step 403: Copy the first file table backed up during the previous synchronization to the intermediate storage device 23 as the third file table. Step 404: Align the third file table with the current first file list D 212. Step 405: Determine whether it is found that at least one first file of the first folder needs to be updated to the intermediate storage device 23. If yes, proceed to step 4〇6, otherwise skip to step 407. Step 406: Copy the first file from the first folder 211 to the mediation device 23, and correspondingly update the second file table, and update the backed up first file table to the current first slot table 212. . Step 407: Align the third file list with the current second play form 222. Step 408: Determine whether the at least one second broadcast to be updated to the second folder 221 in the intermediate storage device 23 is found. If yes, the process proceeds to step 409. Otherwise, the process proceeds to step 410. Step 409: Copy or move the second file from the intermediate storage device 23 to the second data loss 221, and correspondingly update the second file table 222, and save the updated second 16 file table 222 as a backup. Step 410: Determine whether it is found that the second folder 221 needs to be updated to at least one third file of the intermediate storage device 23. If yes, proceed to step 411; otherwise, skip to step 417. Step 411: Copy the third file from the second folder 221 to the intermediate storage device 23, and update the third broadcast table correspondingly. Step 412: Align the third file table with the current first file table 212. Step 413: Determine whether the intermediate storage device 23 needs to be updated to at least one fourth file of the first folder 211, and if yes, proceed to step 414, otherwise, go to step 415, step 414: the fourth file from the intermediate storage device 23 copies or moves to the first folder 211, and correspondingly updates the first file table 212, and updates the backed up first file table to the updated first file table 212. Step 415: Determine whether it is found that at least one fifth file of the first folder 2U needs to be updated to the intermediate storage device 23. If yes, proceed to step 416; otherwise, skip to step 417.
