Description

File management method, desktop display method, device, terminal and medium

Technical Field

The present invention relates to the field of internet technologies, and in particular, to the field of data processing technologies, and in particular, to a file management method, a desktop display method, a file management device, a desktop display device, a terminal, and a computer storage medium.

Background

File management is a collective term for a group of software, managed files, and some data structures required for implementing file management in an operating system, and mainly relates to logical organization and physical organization of files. When the operating system manages files, the file information of the files recently opened by the user is stored in a latest file directory (a license directory) of the operating system, so that the user can conveniently and quickly find the files recently opened through the license directory.

Currently, file operation methods can be classified into standard operation methods and non-standard operation methods, and the standard operation method generally refers to a method of operating a file by entering a system hard disk according to a file path, for example: for a file with a file path of D/A folder/a.docx, the user opens the file according to the method of opening D disc, opening A folder and opening a.docx file, and the operation method is regarded as a standard operation method; the non-standard operation method generally refers to a method of operating a file by an application program; for example: the file a.docx file is a file received and downloaded through instant messaging software, and a user directly opens the file a.docx through the instant messaging software, and the operation method is considered to be a non-standard operation method. In the prior art, when a standard operation method is adopted to operate a file, an operating system responds to an operation instruction to open the file, and meanwhile, the operating system automatically records file information of the operated file and stores the file information into a percent directory; however, if the file operation is performed by adopting the non-standard operation method, the operating system cannot record the file information of the operated file, so that the license directory of the operating system cannot accurately and comprehensively store the file information of the file recently opened by the user.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

An Operating System (OS) is a computer program that manages and controls computer hardware and software resources, and in an embodiment of the present invention, the Operating System may refer to a System that has a process monitoring function and includes a recovery directory, and may include, but is not limited to: windows operating system (Windows operating system), linux operating system, android operating system (Android system), etc. Taking Windows operating system as an example, as shown in FIG. 1, the operating system can be divided into Kernel mode (Kernel Model) and User mode (User Model). The kernel mode part comprises a system service distributor and a driving layer, wherein the system service distributor can be used for realizing communication between the driving layer and the user mode part, and the driving layer can be used for monitoring one or more started processes in the operating system; the user mode portion includes an application layer that includes an application programming interface and one or more applications or the like that can obtain corresponding system services from the kernel mode portion by invoking the application programming interface.

In the embodiment of the present invention, the operating system includes a file management program, which may be an application program located at an application layer, that is, an exe (executable program ) program in the Windows operating system; the file manager may be used to perform management operations on a count directory in an operating system. The method comprises the steps that a license catalog is a user-state file catalog in an operating system, and a license target is used for recording file information of a file which is recently operated in the operating system; the "latest" herein refers to a preset period of time before the current system time of the operating system, which may be set according to actual needs, for example, the preset period of time may be set to 5 minutes, 20 minutes, 10 hours, etc.; for example, the current system time of the operating system is 10:30, and the preset time period is 10 hours: if the user opens file a at 10:15, it can be determined that file a is the most recently operated file. The files may include, but are not limited to, various types of files such as video, audio, documents, pictures, etc., and may be files stored in a system hard disk of an operating system, files downloaded in real time through various application programs in the operating system, or files stored in a cloud of various application programs in the operating system. File information may be used to describe various attributes of a file, which may include, but is not limited to: file path, file name, file size, time parameters of the file, etc.

A process is a running activity of a program in a computer on a certain data set, is a basic unit of resource allocation and scheduling by an operating system, and is a basis of an operating system structure. The processes may include two types, a service process and an application process; the service process refers to a process generated to ensure normal running of the operating system, or refers to a process generated by the operating system to respond to a user performing a file operation by using a standard operation method (for example, opening a file by using a standard operation method). The application process refers to a process generated by an operating system to support normal running of an application program when the application program in an application layer is started, and generally, one application program corresponds to one application process; for example: when an email (Electronic Mail) application program in an application layer is started, an application process corresponding to the email application program is started at a driving layer of an operating system so as to support the normal operation of the email application program; correspondingly, when an application program in the application layer executes file operation, a file operation event generated by an application process corresponding to the application program can be monitored in a driving layer of an operating system; as indicated by the dashed box in fig. 1.

Based on this, the embodiment of the invention provides a file management scheme, which specifically comprises the following steps: when there is a file operation (such as opening a file, modifying a file, etc.) in the operating system, whether the file operation is performed by a standard operation method (such as an operation that a user enters a system hard disk according to a file path to open the file), or the file operation is performed by a non-standard operation method (such as an operation that a user opens the file through an application program), in response to the file operation, a driver layer of the operating system detects process information of a corresponding process (including a service process or an application process), and then the process information is transferred to a file management program to analyze, so that file information of a file that is recently operated can be obtained, and further, the file information of the file that is recently operated can be updated into a license directory of the operating system. As described in the foregoing background art, the operating system has a function of automatically recording file information of files operated by a standard operating method, so in order to save resources and avoid duplicate recording, the file management scheme of the embodiment of the present invention focuses on managing a target file operated by a non-standard operating method, that is, the target process may include an application process generated in response to file operations performed by a non-standard operating method.

In combination with the operating system architecture diagram shown in fig. 1, the working principle of the file management scheme is as follows: (1) the operating system may call a driver layer (driver module) in the kernel mode part to load a system driver through which a hook system API (Application Programming Interface ) is hooked to monitor each started process in the operating system in real time; (2) if a certain target file is subjected to operations such as opening, modifying or editing, the operating system can monitor a target process which is started and has a file operation event in a driving layer, the target process can be an application process, and then the process information of the target process can be acquired, wherein the process information of the target process comprises command line parameters, and the command line parameters at least carry the file information of the target file; (3) the system service distributor transfers the process information of the target process from the driver layer to a file management program (i.e., exe program) in the application layer. (4) After the process information of the target process is acquired, the file management program analyzes the process information of the target process to acquire the file information of the target file, and writes the file information of the target file into a license directory of an operating system.

The file management scheme provided by the embodiment of the invention realizes the management of the recently operated file by acquiring and analyzing the process information; therefore, the corresponding process information can be intercepted and managed only by the existence of the file operation event, so that the file information of the recently operated target file can be timely stored in the license catalog, and the accuracy and the comprehensiveness of the license catalog are ensured.

Based on the above description, the embodiment of the present invention proposes a file management method as shown in fig. 2, and the file management method may be applied to a terminal, where the terminal may include, but is not limited to: smart phones, desktop computers, notebook computers, laptop computers, etc.; the terminal is provided with an operating system, and the operating system comprises a driving layer and a file management program. Referring to fig. 2, the file management method may be executed by a file management program in the above-mentioned operating system, and the file management method may include the following steps S201 to S203:

s201, process information of a target process in an operating system of the terminal is obtained.

The file management program can acquire the process information of a target process in the operating system from a driving layer of the operating system of the terminal, wherein the target process is any process which is started in the operating system and has a file operation event. Specifically, the driver layer may monitor each started process in the operating system in real time, such as process 1, process 2, process 3, process N, and so on in fig. 2. If the user performs file operation on the target file through the target application program, the driving layer can monitor that a corresponding file operation event exists in a target process corresponding to the target application program. In one embodiment, the file manipulation event may include, but is not limited to: file access events (also referred to as file open events), file creation events, file update events, file save events, and so forth.

If the driver layer monitors that one or more started processes have file operation events, one process can be selected from the one or more started processes with file operation events as a target process. The driver layer may then obtain process information of the target process, where the process information of the target process may include a command line parameter, where the command line parameter carries file information of a target file corresponding to a file operation event of the target process, and the command line parameter is a parameter given in a command line when the operating system operates the target process in a command line manner. After the driving layer obtains the process information of the target process, the driving layer can transmit the process information of the target process to the file management program so that the file management program can obtain the process information of the target process.

S202, analyzing the process information of the target process to acquire the file information of the target file, wherein the file information of the target file comprises the file path of the target file.

S203, updating the latest file directory of the operating system according to the file information of the target file.

In steps S202-S203, since the command line parameter in the process information of the target process carries the file information of the target file, after the file management program obtains the process information of the target process, the command line parameter in the process information may be analyzed in step S202, so that the file information of the target file may be obtained, where the file information includes the file path of the target file. In one embodiment, the file information may further include information such as a file name, a file type, a file size, and the like of the target file. After the file information of the target file is acquired, the latest file directory of the operating system may be updated according to the file information of the target file.

In one embodiment, the updating of the latest file directory of the operating system according to the file information of the target file may be: detecting whether file information of a target file exists in a latest file directory of an operating system; if the file information of the target file does not exist in the latest file directory of the operating system, the file information of the target file is added into the latest file directory of the operating system. In one embodiment, the file information of the target file further includes at least one of: file name, file size and time parameters; if the file information of the target file exists in the latest file catalog of the operating system, judging whether the file information of the target file carried in the command line parameter is consistent with the file information of the target file existing in the latest file catalog of the operating system; if the file information of the target file carried in the command line parameters is inconsistent, updating the latest file directory of the operating system. Wherein the time parameter comprises at least one of: creation time parameter, access time parameter, update time parameter, and save time parameter.

Based on the above description, an embodiment of the present invention proposes a file management method as shown in fig. 3, which may be applied to a terminal, which may include, but is not limited to: smart phones, desktop computers, notebook computers, laptop computers, etc.; the terminal is provided with an operating system, and the operating system comprises a driving layer and a file management program. Referring to fig. 3, the file management method may be executed by the file management program in the operating system, and the file management method may include the following steps S301 to S306:

s301, a message notification is acquired from the driver layer.

From the foregoing, the driver layer may monitor each initiated process in the operating system. In the implementation process, the driving layer may load a system driver, and the system driver may call back through a HOOK registry in a HOOK framework in the driving layer, where the HOOK is a system mechanism provided in an operating system to replace "interrupt" under DOS (Disk Operating System ), and may be called "HOOK" or "HOOK", that is, the HOOK framework may be called a HOOK framework; and hooks the system API according to the SSDT (System Services Descriptor Table ) to enable monitoring of started processes in the operating system.

After the driving layer monitors the target process with the file operation event in the started process, the driving layer can intercept the process information of the target process through HOOK, and throw the process information of the target process to the file management program through the policy engine, and send a message notification to the file management program. Specifically, the driving layer may firstly package the process information of the target process, and insert the packaged process information into the event queue to wait for being thrown to the file management program; and then the driving layer can sequentially upload the information (including the packed process information) in the event queue to the file management program through IPC communication (Inter-Process Communication ) according to preset upload logic.

The file management program may obtain the message notification from the driver layer, where the message notification may carry process information of the target process, where the process information of the target process is intercepted by the driver layer when it is detected that the target process is started in the operating system and a file operation event exists.

S302, analyzing the process information of the target process from the message notification.

Because the message notification carries the process information of the target process, the file management program can analyze the message notification after acquiring the message notification, so as to acquire the process information of the target process, and the process information of the target process can comprise command line parameters which carry the file information of the target file corresponding to the file operation event of the target process.

S303, analyzing file information of the target file from command line parameters in the process information of the target process, wherein the file information of the target file comprises a file path of the target file.

As can be seen from the foregoing, since the operating system itself has a function of recording file information of the file operated by the standard operating method, in order to save processing resources, avoid dragging the operating speed of the operating system due to occupation of the processing resources and repeatedly recording the file information, the file management method provided by the embodiment of the present invention focuses on managing the target file operated by the non-standard operating method. That is, if the target process is a service process generated in response to the file operation on the target file using the standard operation method, the operating system may be used to directly record the file information of the target file without wasting processing resources to execute step S303. Therefore, in one embodiment, the process information of the target process may further include a process name of the target process, and after step S302, the method may further include the following steps: (1) obtaining a blacklist, wherein the blacklist comprises at least one name of a non-associated process, the non-associated process refers to a service process generated by an operating system in order to respond to file operation by a user by adopting a standard operation method, or refers to a service process generated by the operating system in order to ensure normal operation of the operating system, and the service process may also open certain files to generate file operation events, but the file operation events are only generated by the inside of the operating system in order to support normal operation and are not generated by actual operation of a target file by the user through an application program; taking Windows operating system as an example, the unassociated process may include: svchost.exe (a system program in the Windows operating system, which is a generic host process name of a service running in a dynamic link library), conhost.exe (Console Host Process, a host process of a command line program), dllhost.exe (a part of the Windows operating system for managing a dynamic link library application), and the like. (2) Judging whether the name of the target process belongs to a blacklist or not; (3) if the name of the target process does not belong to the blacklist, step S303 is performed.

In still another embodiment, the process information of the target process may further include a process name of the target process, and after step S302, the method may further include the following steps: (1) acquiring a white list, wherein the white list can comprise at least one name of an associated process, and the associated process is an application process corresponding to an application program in an operating system; the associated process refers to an application process with file operation capability in an operating system, for example: an application process corresponding to an instant messaging application program, an application process corresponding to an email application program, and the like; (2) judging whether the name of the target process belongs to a white list or not; (3) if the name of the target process belongs to the white list, step S303 is executed.

In yet another embodiment, if the target process is an application process corresponding to an application program, since the command line parameters of different application programs are different, for example, space is included in the command line parameters of some application programs, special characters and escape characters are included in the command line parameters of some application programs, outliers are included in the command line parameters of some application programs, and so on. Therefore, the embodiment of the invention adopts a unified preset parameter format aiming at the command line parameters of different application programs, so that the command line parameters can be analyzed conveniently, and the analysis efficiency is improved. Therefore, after parsing out the process information of the target process in step S302, the following steps may be further included: (1) judging whether the parameter format of the command line parameters in the process information of the target process meets the preset parameter format or not; (2) if yes, executing the step of analyzing the file information of the target file from the command line parameters in the process information of the target process, namely executing step S303; (3) if not, carrying out normalization processing on command line parameters in the process information of the target process according to a preset parameter format; for the normalized command line parameters, a step of parsing file information of the target file from the command line parameters in the process information of the target process is performed, that is, step S303 is performed.

The specific implementation mode of carrying out normalization processing on the command line parameters in the process information of the target process according to the preset parameter format can be as follows: acquiring a filter of a target application program corresponding to a target process; and applying the command line parameters to a preset parameter format by adopting the filter to match so as to normalize the command line parameters.

It should be noted that, the step of determining whether the target process is a service process and the step of determining whether the parameter format of the command line parameter satisfies the preset parameter format may be performed, that is, when the target process is not a service process and the parameter format of the command line parameter satisfies the preset parameter format, step S303 is performed. In one embodiment, after analyzing the process information of the target process, it may be first determined whether the target process is a service process; if not, judging whether the parameter format of the command line parameters meets the preset parameter format; if yes, go to step S303; if not, carrying out normalization processing on the command line parameters. In another embodiment, the step of determining whether the parameter format of the command line parameter satisfies the preset parameter format may be performed first, and then the step of determining whether the target process is a service process may be performed, and if not, the step S303 may be performed. In still another embodiment, the step of determining whether the target process is a service process and the step of determining whether the parameter format of the command line parameter satisfies the preset parameter format may be performed simultaneously, which is not limited herein. In other embodiments, only the step of determining whether the target process is a service process or whether the parameter format of the command line parameter satisfies the preset parameter format may be performed.

S304, verifying the validity of the target file according to the file information of the target file.

Since the user may change the file information of the target file after the file management program obtains the file information of the target file, for example, the file path in the file information of the target file obtained by the file management program is "application a/folder 1", and the user moves the target file from "folder 1" to "folder 2", the actual file path of the target file at this time is changed to "application a/folder 2". In this case, the "no object file in folder 1", i.e., the file path "application a/folder 1" in the acquired file information is an erroneous file path. For another example, the file path in the file information of the target file obtained by the file management program is "application a/folder 1", and the user deletes the target file, and at this time, there is no target file in "folder 1", and the file path "application a/folder 1" is also an erroneous file path. If the error file path is updated to the latest file directory, the user cannot quickly open the target file in the latest file directory, and the user cannot find the target file through the error file path.

Therefore, after the file information of the target file is obtained, the validity of the target file can be checked according to the file information of the target file, so as to judge whether the file path is correct, i.e. whether the target file corresponding to the file path exists. Specifically, when the validity of the target file is verified according to the file information of the target file, if the validity of the target file is verified through the standard API, when the operating system accesses the target file through the standard API, there is a very high probability that the target application program accessing the target file generates file access conflict, thereby affecting the operation of the target application program. Thus, embodiments of the present invention employ a non-preemptive API to check the validity of a target file, which may include, but is not limited to: a memory mapped API, an API that creates temporary folders, etc. The validity of the target file is checked by adopting the non-preemptive API, so that the condition that the operating system and the target application program generate file access conflict can be avoided, and the normal operation of the target application program can be ensured.

Accordingly, in one embodiment, the specific embodiment of verifying the validity of the target file according to the file information of the target file may be: (1) calling a first non-preemptive application programming interface to create a temporary folder; (2) acquiring a target file according to a file path of the target file; (3) and if the target file is successfully stored in the temporary folder, determining that the target file is successfully checked. The non-preemptive first application programming interface in this embodiment may be an API that creates temporary folders.

In still another embodiment, the specific embodiment of verifying the validity of the target file according to the file information of the target file may be: (1) calling a second non-preemptive application programming interface to create a temporary operation area and a mapping relation between the temporary operation area and the memory of an operating system; (2) acquiring a target file according to a file path of the target file, and mapping the target file from a memory of an operating system to a temporary operating area according to the mapping relation; (3) and if the target file is successfully accessed in the temporary operation area, determining that the target file is successfully checked. The non-preemptive second application programming interface in this embodiment may be a memory mapped API.

In other embodiments, the file information may further include a file name of the target file, and before verifying the validity of the target file according to the file information of the target file, the validity of the target file may be further verified preliminarily according to the file name of the target file. Specific: (1) acquiring a white list, wherein the white list comprises at least one file extension of an effective file, and the file extension is also called a suffix name of the file, so that the white list is a mechanism for marking the file type by an operating system; (2) judging whether the file extension of the file name of the target file belongs to a white list or not; (3) if the file extension of the file name of the target file belongs to the white list, executing the step of checking the validity of the target file according to the file information of the target file, namely further adopting a non-preemptive API to check the validity of the target file according to the file path of the target file; and if the file extension name of the file name of the target file does not belong to the white list, determining that the target file is an invalid file. (4) If the target file is an invalid file, the subsequent step of checking the validity of the target file according to the file information of the target file is not executed any more, and processing resources can be saved.

S305, if the verification of the target file is successful, acquiring the file information of the target file.

S306, updating the latest file directory of the operating system according to the file information of the target file.

Based on the description of the above embodiment, the embodiment of the present invention further provides an application scenario diagram of a file management method, as shown in fig. 4. The drive layer of the operating system can monitor each started process in the operating system in real time. The user opens the file 1 (target file) through the application program 1 in the desktop, that is, the user performs a file operation on the target file through the application program 1, and at this time, the application program 1 can trigger the corresponding process 1 (target process) to generate a file operation event. After the driving layer of the operating system monitors that the process 1 generates the file operation event, the process information of the process 1 can be acquired and transferred to the file management program. The file management program may analyze the process information to obtain file information of the file 1, where the file information may include a file path of the file 1; the file manager may then update the file information for file 1 into the last file directory of the operating system. Products in the operating system that rely on information such as the user's most recently opened file (e.g., desktop organizer applications, desktop display applications, etc.) may read file information for one or more files from the most recent file directory, the file information for the one or more files including file 1's file information. And displaying the read file information of the one or more files in a latest file display window of the desktop.

Therefore, on the basis that the operating system has the function of automatically recording the file information of the file operated by the standard operating method, the file management method provided by the embodiment of the invention can also record the file information of the target file operated by the non-standard operating method, so that the accuracy and the comprehensiveness of the license catalog are ensured.
