Optionally, the computer device may be a handheld device such as a smartphone, a terminal device such as a personal computer, or a smart wearable device such as a smart watch, which is not particularly limited in this application.

Figure 1 shows a schematic framework diagram of a computer device 1 provided by an embodiment of the present application.

As shown in FIG. 1 , the computer device 1 includes: a hardware layer 10 , an operating system layer 20 running on the hardware layer 10 , and an application layer 30 running on the operating system layer 20 . The hardware layer 10 includes hardware such as processors, memory, and external storage. The operating system layer 20 is any one or more computer operating systems that implement business processing through processes, such as Linux operating system, Unix operating system, Android operating system, iOS operating system or Windows operating system, etc. The application layer 30 includes application programs such as browsers, address books, word processing software, and instant messaging software.

Specifically, the operating system layer 20 includes a kernel (Kernel) 201, which is the core of the operating system layer 20 and is responsible for managing the system's processes, memory, device drivers, files, network systems, etc., and determines the performance and stability of the system. . The kernel 201 is a bridge connecting the application layer 30 and the hardware layer 10 .

Based on the embodiment shown in Figure 1, Figure 2 shows a schematic frame diagram of a computer device 1 provided by another embodiment of the present application.

As shown in Figure 2, the application program (Application, APP) 301 is a computer program in the application layer 30. It is located in the user space (User Space) of the computer device 1 and can be used and designed by the user.

Relative to the user space, the kernel 201 in the operating system layer 20 is located in the kernel space (Kernel Space) of the computer device 1 . The kernel 201 is independent of user-level applications. The kernel 201 has access to protected memory space and has full access to underlying hardware devices. In order to ensure the security of the kernel 201, the operating system layer 20 generally forces user processes not to directly operate the kernel 201.

Optionally, in the kernel space, the kernel 201 may include: System Call Interface (SCI) 210, Memory Management Unit (MMU) 220, Process Management Program 230, Virtual File System (Virtual File System, VFS) 240, file system (File System, FS) 250 and device driver (Device Driver) program 260 and other functional modules.

Specifically, in the kernel 201, the system call interface (SCI) 210 provides an interface for user space to access the kernel space. Under different hardware architectures of computer devices 1, the methods of entering the kernel space through SCI 210 are different.

The memory management unit (MMU) 220 is used to control data interaction between the memory and the processor in the computer device 1 . Specifically, the MMU 220 receives a memory access request from the processor and controls access to the memory based on the memory access request.

The process management program 230 is a program that manages multiple processes in the operating system. The process management program 230 can be used to implement various functions such as process scheduling, interrupt processing, signal/process priority, context switching, process status management, and progress memory management.

The virtual file system (VFS) 240 is an intermediate processing system between the file system (FS) 250 and the system call interface (SCI) 210. In the embodiment of this application, the computer device 1 can support multiple different types of file systems. As an example but not a limitation, the FS 250 can include: EXT2, EXT3, EXT4, F2FS, rootfs, proc and other types of file systems. .

In order to support different file systems, VFS 240 hides the specific details of the hardware of different file systems, separates file system operations from the specific hardware implementation of different file systems, and provides a unified interface for all devices.

Device driver 260 is one of the main parts of kernel 201. The device driver 260 actually controls the interaction between the operating system layer 20 and the hardware layer 10 . Specifically, in addition to providing a set of abstract interfaces understandable by the operating system layer 20 to complete the interaction between the operating system layer 20 , the device driver 260 is also used to complete specific operation details related to the hardware devices in the hardware layer 10 . Generally speaking, the device driver 260 is related to the control chip of the hardware device.

It can be understood that in the embodiment of the present application, the kernel 201 in the operating system layer 20 and the application program in the application layer 30 are both software modules in the computer device 1, which are specifically implemented as computer programs (or also called computer programs). code). In order to realize the program function, as shown in FIG. 2 , the hardware layer 10 of the computer device 1 needs to include at least one processor 110 . In addition to the processor 110, the hardware layer 10 may also include memories such as a memory 120 and an external memory 130.

Specifically, the function of the processor 110 is mainly to interpret instructions of the computer program and process data in the computer program. The instructions of the computer program and the data in the computer program can be stored in the memory 120 and/or the external memory 130 of the computer device 1 .

Alternatively, the processor 110 may be an integrated circuit chip with signal processing capabilities. By way of example and not limitation, the processor 110 may be a general-purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), or a field programmable gate array. , FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components. Among them, the general-purpose processor is a microprocessor or the like. For example, the processor 110 is a central processing unit (CPU).

Each processor 110 includes at least one processing unit. Optionally, this processing unit is also called a core and is the most important component of the processor. All calculations, receiving commands, storing commands, and processing data of the processor 110 are performed by the core.

The memory 120 is also called main memory, and its function is to temporarily store the operation data in the processor 110 and the data exchanged with the external memory 130. There is a fast data reading and writing speed between the memory 120 and the processor 110 . In addition, the memory 120 can provide running space for processes in the computer device 1. For example, the memory 120 stores computer programs for generating processes. After the computer program is run by the processor 110 to generate a process, the processor 110 allocates corresponding storage space for the process in the memory 120 . The memory 120 stores data generated during the running of the process, such as intermediate data, process data, etc., in the storage space corresponding to the above-mentioned process.

As an example and not a limitation, in the embodiment of the present application, the memory 120 may be a volatile memory. Wherein, the volatile memory may be random access memory (Random Access Memory, RAM). By way of illustration, but not limitation, many forms of RAM are available, such as static random access memory (Static RAM, SRAM), dynamic random access memory (Dynamic RAM, DRAM), and the like.

The external memory 130 can also be called auxiliary memory, which refers to the memory in the computer device 1 except the memory 120 and cache. Optionally, the external memory 130 can be a memory that can still save data after power is turned off. And the external memory 130 can have a relatively large capacity and can store file data such as pictures, videos, text, and application programs in the computer device 1 to meet the user's needs.

As an example and not a limitation, in the embodiment of the present application, the external storage 130 can be a non-volatile memory, a magnetic disk, an optical disk, a U disk (also called a USB flash disk) or a Secure Digital Memory Card (SD Card) etc. Among them, the non-volatile memory may include at least one of the following memories: read-only memory (Read-Only Memory, ROM), programmable read-only memory (Programmable ROM, PROM), erasable programmable read-only memory ( Erasable PROM, EPROM), electrically erasable programmable read-only memory (Electrically EPROM, EEPROM) and flash memory (FLASH). In addition, the disk can be a hard disk (Hard Disk) or a floppy disk (Soft Disk). The hard disk can include: solid state drive (Solid State Drive, SSD), hybrid hard drive (Hybrid Hard Drive, HHD) and mechanical hard drive (Hard Disk Drive, HDD) and so on.

It should be understood that the structure of the computer device 1 listed above is only an illustrative description, and the application is not limited thereto. The computer device 1 in the embodiment of the application includes various software modules or hardware modules in computer systems in the prior art. For example, in terms of hardware modules, the computer device 1 also includes: communication devices, sensor devices, peripheral devices with various functions, and so on.

For the above-mentioned computer device 1, the storage space of the memory 120 mainly affects the running speed of the computer device 1. Therefore, the memory 120 can also be called "operation memory". The storage space of the external memory 130 mainly affects the ability of the computer device 1 to store file data. The storage space of the external memory 130 can be understood as the storage space in the computer device 1 for storing file data.

As an example, when the computer device 1 is a mobile phone, its external memory 130 may be a non-volatile memory, such as FLASH and so on. The non-volatile memory is arranged inside the computer device 1. Due to various factors such as manufacturing cost, the storage space of the non-volatile memory has certain limitations. As the use time of mobile phones increases, more and more files are stored in the non-volatile memory. The remaining storage space of the non-volatile memory is insufficient, which will cause the phone to freeze, thus affecting the user's use of the phone. experience.

Of course, in other examples, the computer device 1 may also be other types of devices, and the external memory 130 may also be other types of memories. Regardless of the type of memory, as the usage time increases, it will face insufficient storage space, resulting in a poor user experience with the computer device 1 .

In order to solve the above problems, cloud disk (or network disk) service came into being. In order to use the cloud disk service, the user needs to download a specific cloud disk application in the computer device 1. The cloud disk application is located in the user space of the computer device, and is used to implement file data interaction between the local storage (such as external memory 130) of the computer device 1 and the cloud disk. During this process, the cloud disk application needs to continuously call the system call interface 210 to enter the kernel space to access files in the local memory. This process consumes a large amount of system resources and affects system operating efficiency. In addition, in this method, using the cloud disk service requires downloading a specific cloud disk application. This method is not universal and the user experience is poor.

In view of this, the present application provides a file operating device that can solve the technical problems of low system operation efficiency of the above computer equipment and poor versatility of cloud disk services.

Optionally, the local memory may be the external memory 130 in the embodiment shown in Figure 2 above.

FIG. 11 shows a schematic structural block diagram of a file operating device 300 provided by another embodiment of the present application.

As shown in Figure 11, in this embodiment of the present application, the file management system 310 includes: an instruction processing subsystem 311 and a first execution subsystem 3121. Wherein, the instruction processing subsystem 311 is configured to obtain the first relocation command of the file, and call the first execution subsystem 3121 according to the first relocation command. The first execution subsystem 3121 is configured to transfer the file data of the file from the local storage to the cloud storage. In this embodiment, the first execution subsystem 3121 may be part of the program code blocks in the execution subsystem 312 in Figure 10 mentioned above.

Through the technical solution of this embodiment, the synchronization of the file data in the local storage of the computer device and the cloud storage can be facilitated, making it convenient for the user to use the file data through the cloud, and improving the user experience. In addition, through the technical solution of this embodiment, the first execution subsystem 3121 is easily called by the upper-layer instruction processing subsystem 311, and executes one-way transmission of file data from local storage to cloud storage, which is beneficial to subsequent processing of file data. Locating problems that occur during the one-way transmission process improves the reliability of the operating device 300 and the computer equipment in which it is located.

Optionally, in the embodiment of the present application, the first execution subsystem 3121 is configured to call the network protocol system 330 in the above embodiment to transmit the file data of the file in the local storage to the cloud storage.

Optionally, as shown in Figure 11, in this embodiment of the present application, the above-mentioned file management system 310 also includes: a local management subsystem 313, which is configured to release the file data of the file occupied in the local memory. storage space, and a relocation mark of the file is written in the local storage. The relocation mark is used to indicate that the file data of the file has been moved to the cloud storage.

Specifically, in the embodiment of the present application, when the first execution subsystem 3121 in the file management system 310 transfers the file data of the file from the local storage to the cloud storage, the local management subsystem in the file management system 310 313 is used to release the storage space occupied by the file data in the local storage. For example, the local management subsystem 313 may truncate the file data size of the file to zero to release the storage space occupied by the file data.

Further, the local management subsystem 313 is also configured to write a relocation mark of the file in the local storage. The relocation mark is used to indicate that the file data of the file has been moved to the cloud storage. During the subsequent operation of the computer equipment, if the user needs to operate the file data of the file, the user can first check the relocation mark of the file in the local storage, and operate the file data of the file based on the check result of the relocation mark. .

Through the technical solution of the embodiment of the present application, the local management subsystem 313 can release the storage space occupied in the local storage by the file data that has been transferred to the cloud storage, thereby saving the storage space in the local storage and ensuring that the local storage has sufficient capacity. The remaining storage space will not cause the computer equipment to freeze, improving the user's experience of using the computer equipment. At the same time, after the first execution subsystem 3121 transfers the file data of the file in the local storage to the cloud storage, the local management subsystem 313 also writes the relocation mark of the file in the local storage, so that the user can subsequently move the file to the cloud storage. During the file operation, the computer device can still access the local storage according to the user's operation command, and perform normal operations on the file data stored in the cloud storage according to the relocation mark in the local storage, so as to further improve the user's use of the computer device. experience.

Optionally, in some implementations, the above-mentioned first execution subsystem 3121 is also configured to determine whether the file data of the file exists in the cloud storage. If it is determined that the file data of the file does not exist in the cloud storage, the first execution subsystem 3121 is configured to transfer the file data of the file in the local storage to the cloud storage.

Specifically, in this embodiment, when the instruction processing subsystem 311 receives the first relocation command of the file and calls the first execution subsystem 3121, the first execution subsystem 3121 first determines whether the file already exists in the cloud storage. , when it is determined that the file does not exist in the cloud storage, it can be determined that the currently received first relocation command is a valid relocation command, and the subsequent file data of the file in the local storage is transferred to the cloud storage. On the contrary, if it is determined that the file has been stored in the cloud storage, it means that the first relocation command currently received is an error command and no subsequent actions will be performed.

As an example and not a limitation, the first execution subsystem 3121 can determine whether the file already exists in the cloud storage by checking whether the relocation mark of the file exists in the local storage. Through this implementation, the local storage can be accessed conveniently, and whether the file currently to be relocated exists in the cloud storage can be determined based on the relocation mark therein. The entire solution is easy to implement and the determination speed is fast. Of course, in other examples, the first execution subsystem 3121 can also determine whether the file to be relocated already exists in the cloud storage through other methods. This embodiment of the present application does not limit this specific determination method.

Through the technical solution of this embodiment, the first execution subsystem 3121 determines whether the file data of the file exists in the cloud storage before executing the file data relocation according to the first relocation command of the file, thereby preventing the wrong first relocation of the file. Under the relocation command, file data relocation is performed repeatedly or invalidly, causing a waste of system resources and affecting file storage performance. Through the technical solution of this embodiment, the first execution subsystem 3121 has an error prevention mechanism and can cope with abnormal instructions. Therefore, the overall performance of the operating device 300 and the computer equipment where it is located can be improved.

Specifically, in this embodiment of the present application, contrary to the above-mentioned first relocation command, the second relocation command is used to instruct the file data of the file to be relocated from the cloud storage to the local storage, and the execution subsystem 312 includes an independent second relocation command. The execution subsystem 3121 is called by the upper-layer instruction processing subsystem 311 and executes the above-mentioned second relocation command.

Through the technical solution of the embodiment of the present application, the second execution subsystem 3122 is easily called by the upper-layer instruction processing subsystem 311, and performs one-way transmission of file data from cloud storage to local storage, which is beneficial to subsequent file data in the Locating problems that occur during the one-way transmission further improves the reliability of the operating device 300 and the computer equipment where it is located.
