In this embodiment, the storage 110 includes a hard disk 111 (eg, HDD, SSD, etc.) and a non-volatile memory 112. The storage 110 is also used to store buffered or permanent data, software modules, application programs, copy history 113 and other data or files, and the detailed content thereof will be described in detail in subsequent embodiments.

處理器150與儲存器110及傳輸介面130耦接，並可以是中央處理單元(CPU)，或是其他可程式化之一般用途或特殊用途的微處理器(Microprocessor)、數位信號處理器(DSP)、可程式化控制器、特殊應用積體電路(ASIC)或其他類似元件或上述元件的組合。在本發明實施例中，處理器150用以執行電腦系統1的所有作業，且可載入並執行儲存器110所記錄的各軟體模組、檔案及資料。The processor 150 is coupled to the memory 110 and the transmission interface 130, and may be a central processing unit (CPU), or other programmable general-purpose or special-purpose microprocessor (Microprocessor), digital signal processor (DSP) ), programmable controller, special application integrated circuit (ASIC) or other similar components or a combination of the above components. In the embodiment of the present invention, the processor 150 is used to perform all operations of the computer system 1, and can load and execute various software modules, files, and data recorded in the storage 110.

外部儲存裝置5可以是隨身碟、記憶卡、隨身或行動硬碟等儲存媒介，外部儲存裝置5亦可能是平板電腦、智慧型手機等具有儲存器的電子裝置。外部儲存裝置5具有與傳輸介面130相符/相容的介面，以可插拔地透過傳輸介面130與電腦系統1連接。於本實施例中，外部儲存裝置5儲存一個或更多個外部檔案51(例如，執行檔、文件檔、影片檔、音樂檔等)。The external storage device 5 may be a storage medium such as a flash drive, a memory card, a portable or mobile hard drive, and the external storage device 5 may also be an electronic device with a memory such as a tablet computer or a smart phone. The external storage device 5 has an interface that is compatible/compatible with the transmission interface 130, and is removably connected to the computer system 1 through the transmission interface 130. In this embodiment, the external storage device 5 stores one or more external files 51 (eg, execution files, document files, video files, music files, etc.).

為了方便理解本發明實施例的操作流程，以下將舉諸多實施例詳細說明本發明實施例中電腦系統1對外部檔案51的處理流程。下文中，將搭配電腦系統1的各項元件及模組說明本發明實施例所述之方法。本方法的各個流程可依照實施情形而隨之調整，且並不僅限於此。In order to facilitate understanding of the operation flow of the embodiment of the present invention, a number of embodiments will be given below to describe in detail the processing flow of the computer system 1 on the external file 51 in the embodiment of the present invention. In the following, the methods described in the embodiments of the present invention will be described with various components and modules of the computer system 1. The various processes of the method can be adjusted according to the implementation situation, and it is not limited to this.

圖2是依據本發明一實施例外部檔案51的容錯處理方法的流程圖。請參照圖2，假設外部儲存裝置5透過傳輸介面130與電腦系統1連接。而電腦系統1可提供檔案管理程式呈現外部儲存裝置5所儲存的外部檔案51，以供使用者透過輸入裝置(例如，滑鼠、鍵盤、觸控面板等)對外部檔案51進行開啟、編輯、執行、複製等檔案操作。而處理器150反應於使用者的檔案操作，對來自外部儲存裝置5的外部檔案51進行對應的檔案操作(即，開啟、編輯、執行、複製等)(步驟S210)。2 is a flowchart of a fault-tolerant processing method of an external file 51 according to an embodiment of the invention. Referring to FIG. 2, it is assumed that the external storage device 5 is connected to the computer system 1 through the transmission interface 130. The computer system 1 can provide a file management program to present the external files 51 stored in the external storage device 5 for the user to open, edit, and edit the external files 51 through the input device (eg, mouse, keyboard, touch panel, etc.) Execute, copy and other file operations. In response to the user's file operation, the processor 150 performs corresponding file operations (ie, opening, editing, executing, copying, etc.) on the external file 51 from the external storage device 5 (step S210).

在對外部檔案51執行檔案操作的過程中，若遇到任何異常情況(例如，外部儲存裝置5拔離傳輸介面130、外部儲存裝置5毀損等)，則現有技術會將當前的檔案操作中斷。也就是說，若外部檔案51僅儲存在外部儲存裝置5中，任何異常情況都會使檔案操作中斷。為了避免前述問題，本發明實施例係先將外部檔案51複製/儲存/暫存到電腦系統的儲存器110的第一檔案路徑下(步驟S230)，而之後接續對儲存在儲存器110的外部檔案51進行原先的檔案操作。In the process of performing file operations on the external file 51, if any abnormal conditions are encountered (for example, the external storage device 5 is disconnected from the transmission interface 130, the external storage device 5 is damaged, etc.), the current technology will interrupt the current file operation. That is to say, if the external file 51 is only stored in the external storage device 5, any abnormal situation will interrupt the file operation. In order to avoid the foregoing problems, the embodiment of the present invention first copies/stores/temporates the external file 51 to the first file path of the storage 110 of the computer system (step S230), and then continues to store the external storage in the storage 110 The file 51 performs the original file operation.

具體而言，請參照圖3是依據本發明一實施例的外部檔案暫存的流程圖。當外部檔案51被開啟時，處理器150會取得外部檔案51的檔案大小、在外部儲存裝置5中的檔案路徑，再判斷外部檔案51開啟後的執行時間是否超過門檻值(例如，30秒、1分鐘、5分鐘等)(步驟S310)。若執行時間尚未超過門檻值但外部檔案51已被關閉或結束/停止對外部檔案51的檔案操作，則處理器150不會(禁能)將外部檔案51複製到儲存器110。另一方面，若執行時間已超過門檻值，則處理器150會將外部檔案51複製到儲存器110。需說明的是，判斷執行時間的機制是避免使用者無意開啟外部檔案51、不需要過長(例如超過門檻值)的執行時間或其他狀況，從而節省儲存器110的儲存空間。然而，在其他實施例中，處理器150亦可能不考慮執行時間，只要外部檔案51被開啟即直接將外部檔案51複製到儲存器110。Specifically, please refer to FIG. 3, which is a flowchart of temporary storage of an external file according to an embodiment of the invention. When the external file 51 is opened, the processor 150 will obtain the file size of the external file 51 and the file path in the external storage device 5, and then determine whether the execution time after the external file 51 is opened exceeds the threshold (for example, 30 seconds, 1 minute, 5 minutes, etc.) (step S310). If the execution time has not exceeded the threshold but the external file 51 has been closed or the file operation on the external file 51 has been closed/stopped, the processor 150 will not (disable) copy the external file 51 to the storage 110. On the other hand, if the execution time has exceeded the threshold, the processor 150 will copy the external file 51 to the storage 110. It should be noted that the mechanism for determining the execution time is to prevent the user from unintentionally opening the external file 51, and does not require an excessively long (for example, exceeding a threshold) execution time or other conditions, thereby saving storage space of the storage 110. However, in other embodiments, the processor 150 may not consider the execution time, as long as the external file 51 is opened, the external file 51 is directly copied to the storage 110.

接著，處理器150判斷電腦系統1是否存在非揮發性記憶體112(步驟S320)。具體而言，非揮發性記憶體112結合傳統儲存裝置及記憶體特性，使儲存的檔案不會因電腦系統1斷電而消失，其傳輸速度更比傳統硬碟或固態硬碟更快。若將外部檔案51儲存在非揮發性記憶體112中，則相較於硬碟111，對非揮發性記憶體112的存取速度快上許多。因此，本發明實施例優先考慮將外部檔案51儲存在非揮發性記憶體112中。若電腦系統1沒有內建非揮發性記憶體112，則處理器150將外部檔案51儲存到硬碟111(步驟S330)。Next, the processor 150 determines whether the non-volatile memory 112 exists in the computer system 1 (step S320). Specifically, the non-volatile memory 112 combines traditional storage devices and memory characteristics so that the stored files will not disappear when the computer system 1 is powered off, and its transfer speed is faster than that of the conventional hard disk or solid-state hard disk. If the external file 51 is stored in the non-volatile memory 112, compared with the hard disk 111, the access speed to the non-volatile memory 112 is much faster. Therefore, the embodiment of the present invention preferentially stores the external file 51 in the non-volatile memory 112. If the computer system 1 has no built-in non-volatile memory 112, the processor 150 stores the external file 51 to the hard disk 111 (step S330).

此外，非揮發性記憶體112的儲存空間有限，且當前製造非揮發性記憶體112的成本相較於硬碟111更高，使得硬碟111的空間通常比非揮發性記憶體112更大。因此，若電腦系統1內建有非揮發性記憶體112，則處理器150會進一步判斷非揮發性記憶體112的剩餘儲存空間是否小於容許空間(例如，500MB、100MB、總儲存空間的百分之75等)(步驟S340)，並依據非揮發性記憶體112的剩餘儲存空間決定將外部檔案51複製到非揮發性記憶體112及硬碟111中的一者。若剩餘儲存空間小於容許空間，則處理器150將外部檔案51儲存到硬碟111(步驟S330)。另一方面，若剩餘儲存空間未小於容許空間，則處理器150將外部檔案51儲存到非揮發性記憶體112 (步驟S350)。值得注意的是，處理器150可能會對儲存在儲存器110的外部檔案51重新命名(例如，原檔名+使用者帳號+系統時間、原檔名+不同序號等)，以避免重複儲存或檔案內容並非最近修改的。或者，當欲複製外部檔案51時，處理器150亦可能是直接將儲存器110中先前儲存的外部檔案51刪除，再複製當前開啟的外部檔案51到儲存器110中。In addition, the storage space of the non-volatile memory 112 is limited, and the current cost of manufacturing the non-volatile memory 112 is higher than that of the hard disk 111, so that the space of the hard disk 111 is usually larger than that of the non-volatile memory 112. Therefore, if the non-volatile memory 112 is built in the computer system 1, the processor 150 will further determine whether the remaining storage space of the non-volatile memory 112 is less than the allowable space (eg, 500MB, 100MB, percentage of the total storage space) 75) (step S340), and decide to copy the external file 51 to one of the non-volatile memory 112 and the hard disk 111 according to the remaining storage space of the non-volatile memory 112. If the remaining storage space is smaller than the allowable space, the processor 150 stores the external file 51 to the hard disk 111 (step S330). On the other hand, if the remaining storage space is not less than the allowable space, the processor 150 stores the external file 51 to the non-volatile memory 112 (step S350). It is worth noting that the processor 150 may rename the external file 51 stored in the storage 110 (eg, original file name + user account + system time, original file name + different serial number, etc.) to avoid repeated storage or The content of the file was not recently modified. Or, when copying the external file 51, the processor 150 may directly delete the previously stored external file 51 in the storage 110, and then copy the currently opened external file 51 to the storage 110.

另需說明的是，在其他實施例中，處理器150亦可能不考慮非揮發性記憶體112的容許空間、或直接將外部檔案51儲存到硬碟111。此外，在一些實施例中，電腦系統1可能僅包括硬碟111及非揮發性記憶體112的其中一者，則處理器150直接將外部檔案51儲存到所具有的儲存器110即可。It should be further noted that, in other embodiments, the processor 150 may not consider the allowable space of the non-volatile memory 112 or directly store the external file 51 to the hard disk 111. In addition, in some embodiments, the computer system 1 may only include one of the hard disk 111 and the non-volatile memory 112, and the processor 150 may directly store the external file 51 to the storage 110 provided.

待外部檔案51完全複製/儲存在儲存器110後，處理器150會搜尋對外部檔案51執行檔案操作的所屬程序(process)(步驟S250、S360)。具體而言，若外部檔案51為文件檔、影像檔、音樂檔等非執行檔，則外部檔案51被使用者選擇開啟後，處理器150會呼叫對應的應用程式或反應於使用者手動選擇應用程式，以透過此對應的應用程式來開啟外部檔案51。而若外部檔案51為執行檔，則處理器150會直接執行此執行檔。值得注意的是，這些應用程式或執行檔被執行後，電腦系統1的作業系統將形成對應程序，以作為已執行程式的實體。而此程序會記錄當前處理檔案的檔案來源(或是磁區來源，以檔案路徑表示)。After the external file 51 is completely copied/stored in the storage 110, the processor 150 searches for the process to perform the file operation on the external file 51 (steps S250, S360). Specifically, if the external file 51 is a non-executable file such as a document file, an image file, a music file, etc., after the external file 51 is selected to be opened by the user, the processor 150 will call the corresponding application program or respond to the user manually selecting the application Program to open the external file 51 through the corresponding application program. If the external file 51 is an executable file, the processor 150 will directly execute the executable file. It is worth noting that after these applications or executable files are executed, the operating system of the computer system 1 will form a corresponding program as the entity of the executed program. And this process will record the file source of the file currently processed (or the source of the magnetic field, represented by the file path).

接著，若外部檔案51是複製到儲存器110的第一檔案路徑下，處理器150則將程序的檔案來源修改成儲存器110儲存外部檔案51的第一檔案路徑(步驟S270、S370)。例如，原先外部檔案51在外部儲存裝置5的檔案路徑為“E:\ABC.EXE”，則所屬程序的檔案來源即為“E:\ABC.EXE”。接著，此外部檔案51複製到儲存器110中“D:\ABC.EXE”的檔案路徑下，處理器150便將所屬程序的檔案來源修改成“D:\ABC.EXE”。Then, if the external file 51 is copied to the first file path of the storage 110, the processor 150 modifies the file source of the program to the first file path of the storage 110 to store the external file 51 (steps S270, S370). For example, if the file path of the external file 51 in the external storage device 5 is “E:\ABC.EXE”, the file source of the associated program is “E:\ABC.EXE”. Then, the external file 51 is copied to the file path of "D:\ABC.EXE" in the storage 110, and the processor 150 changes the file source of the associated program to "D:\ABC.EXE".

由於程序的檔案來源已置換成電腦系統1的第一檔案路徑且外部檔案51已複製到儲存器110中，因此處理器150事實上是對儲存器110中的外部檔案51執行檔案操作。而反應於對儲存器110中外部檔案51的檔案操作的任何異常情況(例如，外部儲存裝置5與電腦系統1分離、外部儲存裝置5毀損等)，處理器150都能接續執行檔案操作而不中斷(步驟S290)，並確保當前執行應用程式或執行檔不會出現錯誤訊息或被強制關閉。Since the file source of the program has been replaced with the first file path of the computer system 1 and the external file 51 has been copied to the storage 110, the processor 150 is actually performing a file operation on the external file 51 in the storage 110. In response to any abnormality in the file operation of the external file 51 in the storage 110 (for example, the external storage device 5 is separated from the computer system 1, the external storage device 5 is damaged, etc.), the processor 150 can continue to execute the file operation without Interrupt (step S290), and ensure that the currently running application or execution file will not display an error message or be forced to close.

需說明的是，為了避免因使用者對外部檔案51修改而使儲存器110與外部儲存裝置5所記錄外部檔案51的內容不一致，在對外部檔案51進行檔案操作的過程中，處理器150可能會定時(例如，每30秒、每一分鐘等)或反應於內容有修改，而將儲存器110中的外部檔案51複製到外部儲存裝置5中。It should be noted that, in order to prevent the content of the external file 51 recorded by the storage 110 and the external storage device 5 from being inconsistent due to the modification of the external file 51 by the user, during the file operation on the external file 51, the processor 150 may The external file 51 in the storage 110 is copied to the external storage device 5 periodically (for example, every 30 seconds, every minute, etc.) or in response to the content being modified.

值得注意的是，本案實施例的容錯機制是將外部檔案51複製到儲存器110中，若外部檔案51之複製作業的執行過程中發生異常情況，將導致複製失敗且待外部儲存裝置51重新連接電腦系統1後檔案路徑的邏輯位址可能會變動。因此，本發明另提出針對外部檔案51之複製作業(即，針對檔案操作為複製作業)的容錯機制。It is worth noting that the fault tolerance mechanism of the embodiment of the present invention is to copy the external file 51 to the storage 110. If an abnormal situation occurs during the execution of the copy operation of the external file 51, the copy will fail and the external storage device 51 will be reconnected After the computer system 1, the logical address of the file path may change. Therefore, the present invention also proposes a fault tolerance mechanism for the copy operation of the external file 51 (that is, the file operation is a copy operation).

圖4是依據本發明一實施例的複製作業的流程圖。請參照圖4，在前述步驟S330及S340中或是反應於使用者直接對外部檔案51的複製操作，處理器150會複製外部檔案51至儲存器110，並記錄此對應複製作業的複製歷程113(步驟S410)。此複製歷程113可以是日誌檔形式，並記錄有外接儲存裝置5的識別資訊(例如，類型(disk type)、序號、廠牌等)、複製作業的進度百分比及外部檔案51儲存在外部儲存裝置的第二檔案路徑。4 is a flowchart of a copy operation according to an embodiment of the invention. Referring to FIG. 4, in the foregoing steps S330 and S340 or in response to the user's direct copy operation of the external file 51, the processor 150 copies the external file 51 to the storage 110 and records the copy history 113 corresponding to the copy operation (Step S410). The copy history 113 may be in the form of a log file, and records the identification information of the external storage device 5 (eg, disk type, serial number, brand, etc.), the progress percentage of the copy operation, and the external file 51 stored in the external storage device The second file path.

接著，處理器150判斷是否有異常情況(例如，電腦系統1斷電、外部儲存裝置5移除等)(步驟S420)。若無異常情況發生，則處理器150繼續複製作業並記錄複製歷程113(返回步驟S410)。另一方面，若有異常情況發生(代表複製作業失敗)，處理器150即依據最近的複製歷程113來進行外部檔案容錯還原(步驟S5)。Next, the processor 150 determines whether there is an abnormal situation (for example, the computer system 1 is powered off, the external storage device 5 is removed, etc.) (step S420). If no abnormality occurs, the processor 150 continues the copy operation and records the copy history 113 (return to step S410). On the other hand, if an abnormal situation occurs (representing the failure of the copy operation), the processor 150 performs external file fault-tolerant restoration according to the latest copy history 113 (step S5).

圖5是依據本發明一實施例的外部檔案容錯還原S5的流程圖。請參照圖5，處理器150將依據複製歷程113中的識別資訊(例如，類型、序號等)來搜尋電腦系統1的作業系統是否有符合原先外部儲存裝置5的識別資訊(步驟S510)，以確認電腦系統1是否偵測(或連接)到外部儲存裝置5(步驟S520)。若沒有偵測到外部儲存裝置5，則代表外部儲存裝置5無法即時連接到電腦系統1或損壞無法及時復原。另一方面，若處理器150偵測到外部儲存裝置5，則處理器150將依據複製歷程113中的第二檔案路徑尋找外部儲存裝置5中符合的檔案路徑(步驟S530)，並判斷是否偵測到相符的檔案路徑(步驟S540)。若自外部儲存裝置5沒有偵測到相符的第二檔案路徑，則外部檔案51將視為不在外部儲存裝置5中。FIG. 5 is a flowchart of external file fault recovery S5 according to an embodiment of the invention. Referring to FIG. 5, the processor 150 will search the operating system of the computer system 1 according to the identification information (for example, type, serial number, etc.) in the copy history 113 for the identification information of the original external storage device 5 (step S510), Confirm whether the computer system 1 detects (or connects) to the external storage device 5 (step S520). If the external storage device 5 is not detected, it means that the external storage device 5 cannot be connected to the computer system 1 in real time or damaged and cannot be recovered in time. On the other hand, if the processor 150 detects the external storage device 5, the processor 150 will search for a matching file path in the external storage device 5 according to the second file path in the copy history 113 (step S530), and determine whether to detect it. A matching file path is detected (step S540). If no matching second file path is detected from the external storage device 5, the external file 51 will be regarded as not in the external storage device 5.

另一方面，若外部儲存裝置5有偵測到相符的檔案路徑(即，外部檔案51儲存在外部儲存裝置5中的第二檔案路徑)，則處理器150計算接續複製作業的還原位址並接續自此第二檔案路徑複製外部檔案51中尚未複製的部分(步驟S550)。具體而言，本發明實施例是採用接續複製的方式來提升恢復複製作業的效率。處理器150會基於複製歷程113中的進度百分比(即，複製作業中斷(或異常情況發生)前或當下的進度百分比)及外部檔案51儲存在外部儲存裝置5的實體位址中的起始位址，來決定異常情況發生時的終止位址。處理器150再依據此終止位址來決定還原位址。而此還原位址是基於公式(1)：

…(1) RDC是還原位址，P是複製歷程113所記錄中斷前的進度百分比，T是外部檔案51儲存在外部儲存裝置5的終止位址，而I是外部檔案51儲存在外部儲存裝置5的起始位址。接著，處理器150即可依據此還原位址來接續複製作業，並判斷是否完成複製作業(即，進度百分比為百分之百)(步驟S560)。若尚未完成複製作業，則處理器150持續進行複製作業至完成。On the other hand, if the external storage device 5 detects a matching file path (ie, the second file path where the external file 51 is stored in the external storage device 5), the processor 150 calculates the restoration address of the subsequent copy operation and Next, the part of the external file 51 that has not been copied is copied from this second file path (step S550). Specifically, the embodiment of the present invention adopts the method of continuous copying to improve the efficiency of the recovery copying operation. The processor 150 will store the external file 51 in the physical address of the external storage device 5 based on the percentage of progress in the replication history 113 (ie, the percentage of progress before or when the replication operation is interrupted (or an abnormal situation occurs)). Address to determine the termination address when an abnormal situation occurs. The processor 150 then determines the restoration address according to the termination address. The restoration address is based on formula (1):

…(1) RDC is the restore address, P is the percentage of progress before the interruption recorded in the copy history 113, T is the termination address of the external file 51 stored in the external storage device 5, and I is the external file 51 stored in the external storage device The starting address of 5. Then, the processor 150 can continue the copy operation according to the restored address, and determine whether the copy operation is completed (ie, the progress percentage is 100%) (step S560). If the copy operation has not been completed, the processor 150 continues the copy operation until it is completed.

舉例而言，使用者播放隨身碟(即，外部儲存裝置5)中的音樂檔(即，外部檔案51)。而此音樂檔播放一分鐘後，處理器150開始複製此音樂檔至儲存器110。假設複製作業的進度百分比到百分之35時，使用者不小心將隨身碟拔離電腦系統1。假設音樂檔的檔案大小為10MB，且其區塊起始位址為0×5000，則終止位址為

。處理器150便自隨身碟中位址為0×2935128開始接續複製作業。For example, the user plays the music file (ie, external file 51) in the flash drive (ie, external storage device 5). After the music file is played for one minute, the processor 150 starts to copy the music file to the storage 110. Assuming that the progress percentage of the copy operation reaches 35%, the user accidentally pulls the pen drive away from the computer system 1. Assuming that the file size of the music file is 10MB and its block start address is 0×5000, the end address is

. The processor 150 starts the copy operation from the address 0x2935128 in the flash drive.

另值得注意的是，若步驟S210中處理器150所接收使用者的檔案操作是複製作業，則處理器150會將外部檔案51複製到此複製操作所指定的電腦系統1的第三檔案路徑下，並仍會執行步驟S230的複製作業。由於步驟S230的複製作業可能將外部檔案51儲存於非揮發性記憶體112，結合非揮發性記憶體112的高速存取特性，因此外部檔案51能更快完整儲存到電腦系統1中。而反應於確認外部檔案51已完整複製到使用者的複製操作所指定的第三檔案路徑下，為了避免空間浪費，處理器115會將步驟S230所儲存的第一檔案路徑下的外部檔案51刪除。It is also worth noting that if the file operation of the user received by the processor 150 in step S210 is a copy operation, the processor 150 will copy the external file 51 to the third file path of the computer system 1 specified by the copy operation , And will still execute the copy job in step S230. Since the copying operation in step S230 may store the external file 51 in the non-volatile memory 112, combined with the high-speed access characteristics of the non-volatile memory 112, the external file 51 can be quickly and completely stored in the computer system 1. In response to confirming that the external file 51 has been completely copied to the third file path specified by the user's copy operation, in order to avoid wasting space, the processor 115 deletes the external file 51 under the first file path stored in step S230 .

本揭露的另一範例實施例提出一種電腦程式產品，用以執行上述外部檔案51的容錯處理方法的各個步驟(圖2~圖5所示實施例)。此電腦程式產品包括多個程式指令，且電腦系統1中的處理器150載入並執行這些程式指令之後，可完成上述的容錯處理方法以及實現電腦系統1的功能。Another exemplary embodiment of the present disclosure provides a computer program product for executing the steps of the above-mentioned fault-tolerant processing method of the external file 51 (the embodiments shown in FIGS. 2 to 5 ). The computer program product includes a plurality of program instructions, and after the processor 150 in the computer system 1 loads and executes the program instructions, the above fault-tolerant processing method and the functions of the computer system 1 can be completed.
