Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the embodiments of the present invention, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated object, indicating that there may be three relationships, for example, a and/or B, which may indicate: a exists singly, A and B exist simultaneously, and B exists singly, wherein A and B can be singular or plural. In the description of the present invention, the character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
If a plurality of electronic files are directly copied to the mobile device, the copying speed is very slow if the number of the electronic files is large; if a plurality of electronic files are copied in a compressed package mode by packaging, the electronic files need to be decompressed and then utilized when being utilized on the mobile device, and therefore more storage space and system resources of the mobile device are occupied. In order to overcome the two technical defects, an embodiment of the present invention provides an electronic file packaging method, where when a plurality of electronic files on a computer device need to be transmitted to a mobile device, a plurality of electronic files to be moved are traversed first to obtain attribute information and file contents of each electronic file; the attribute information of the electronic file comprises a file name, a file type and a file size; and then writing the attribute information and the file content of each electronic file into an empty package file to obtain an electronic file package file. Thus, the electronic files are packaged into the electronic file packaging body file, so that the time spent when the electronic files are transmitted to the mobile equipment is short. And after the mobile equipment receives the electronic file packaging body file, the attribute information and the file content in the electronic file packaging body file can be directly read without decompression, so that more storage space and processor resources are saved.
Hereinafter, the electronic file packaging method provided by the present invention will be described in detail by using several specific embodiments and drawings. It is to be understood that the following detailed description may be combined with other embodiments, and that the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 is a schematic flowchart of an electronic file packaging method according to an embodiment of the present invention, where the electronic file packaging method can be executed by a software and/or hardware device. The hardware device may be an embedded device, or a personal computer, or a device such as a server. As shown in fig. 1, the electronic file packaging method includes:
s101, traversing a plurality of electronic files to be moved to acquire attribute information and file contents of each electronic file; the attribute information of the electronic file comprises a file name, a file type and a file size.
Generally, an electronic file mainly includes two parts, namely attribute information and file content, where the attribute information is used to describe or mark a file name, a file type and a file size of the electronic file, for example, the file name is "zhang san personal profile", and the file type may also be understood as a file format, for example, the file type is a TXT format file, a DOC format file or a PPT format file, and the like. The file size indicates the amount of storage space occupied by the electronic file. The content of the file, i.e. the content information contained in the electronic file, may be in a text format, a picture, a type of video or audio. For example, an electronic file having a file name of "zhang san person profile" corresponds to the personal information or personal history information of zhang san in text format.
For example, the attribute information of the electronic file further includes storage structure information of a plurality of subfiles in each electronic file, for example, a plurality of subfiles are included in one electronic file, each subfile may include a plurality of subfiles, and the storage structure information refers to a storage location of each subfile in the current electronic file and a storage location of a file subordinate to each subfile.
For example, an electronic file encapsulation module or electronic file encapsulation software is installed on the computer device, and the electronic file encapsulation software is opened, so that the storage location on the computer device can be browsed. Then, the user selects all electronic files to be packaged, and after the electronic files are packaged by clicking, electronic file packaging software can automatically traverse all the electronic files to obtain the file name, the file type, the file size, the storage structure information of the sub files and the file content of each electronic file. At the same time, the electronic file packaging software also creates a temporary copy of all electronic files in a temporary directory.
S102, creating an empty package file.
Illustratively, an empty storable capsule file is created, i.e., a single complete transport file that includes a file header and file contents. For example, the electronic file packaging software creates an empty package file on the default electronic file package output path.
S103, determining the storage position information of each electronic file in the empty package file according to the file size of each electronic file.
The storage position information of each electronic file comprises an attribute information storage position and a file content storage position, wherein the attribute information storage position is used for storing the attribute information of the electronic file, and the file content storage position is used for storing the file content of the electronic file.
After the storage position information of each electronic file in the empty packaging body file is determined, the storage position information of each electronic file in the empty packaging body file is updated into the attribute information corresponding to the electronic file, and therefore the storage position of the file content of the electronic file can be determined according to the attribute information.
In an example, determining storage location information of each electronic file in an empty package file according to a file size of each electronic file specifically includes:
determining the attribute information storage position of the attribute information of the electronic file in the empty package file according to the size of the attribute information of each electronic file; and determining the file content storage position of the file content of the electronic file in the empty package file according to the size of the file content of each electronic file.
And S104, sequentially writing each electronic file into the empty package file according to the storage position information of each electronic file in the empty package file to obtain an electronic file package file.
Illustratively, according to the storage location information of each electronic file in the empty package file, sequentially writing each electronic file into the empty package file to obtain an electronic file package file, which specifically includes:
sequentially writing the attribute information of each electronic file into an empty packaging body file according to the attribute information storage position of each electronic file; and sequentially writing the file contents of the electronic files into the empty package files according to the file content storage positions of the electronic files to obtain the electronic file package files.
In other words, an empty package file is first created, and then the file contents and attribute information of the respective electronic files are sequentially written into the empty package file. Specifically, the temporary copies of all electronic files created in the temporary directory may be sequentially written into the empty capsule file. For example, the attribute information of all electronic files is written into an empty package file sequentially, the attribute information of each electronic file may further include storage location information of the electronic file in the package file, and a start location and an end location corresponding to the file content of the electronic file may be determined according to the size of the file content. Generally, the attribute information of each electronic file is sequentially stored in the head position of an empty package file, and after the attribute information of all the electronic files is stored, the file content of each electronic file is sequentially stored, wherein the attribute information storage sequence of the electronic files corresponds to the file content storage sequence. As can be seen from the above, the header part of the packaged electronic file is the file name, file type, file size, storage structure information of a plurality of subfiles, and the like of each electronic file stored sequentially. After the attribute information of all the electronic files is stored, the file contents are stored according to a mode corresponding to the storage sequence of the attribute information of the electronic files, namely the storage position of the file attribute signal is advanced, and then the storage position of the file contents is advanced, so that a plurality of electronic files are packaged into an integral electronic file package file.
For example, in order to facilitate storage and transmission of the electronic files, before the attribute information of each electronic file is sequentially written into the empty package file according to the attribute information storage location of each electronic file, the electronic file packaging method further includes encrypting the storage location information and the attribute information of each electronic file into first byte information. Namely, the storage position information and the attribute information of each electronic file are converted into corresponding byte information for storage.
Meanwhile, before the file contents of each electronic file are sequentially written into an empty package file according to the file content storage position of each electronic file, the electronic file packaging method further comprises the following steps: and encrypting the file content corresponding to the electronic file into second byte information. That is, the file content corresponding to the electronic file is also converted into byte information for storage.
If a plurality of electronic files are transmitted to the mobile device in sequence, the mobile device needs to calculate the size of each electronic file, allocate a storage position to each electronic file, and wait for only one electronic file to be stored and then continue to store the next electronic file, which greatly affects the transmission efficiency of the electronic files.
It can be seen that, by using the electronic file packaging method of the embodiment, information of a plurality of electronic files can be read and uniformly packaged to obtain an integral electronic file package body file. Therefore, when the electronic file packaging body file is transmitted to the mobile equipment, the mobile equipment only needs to calculate and determine a storage position according to the size of the electronic file packaging body file, and then continuous storage can be completed, so that the file transmission and storage efficiency is improved.
Fig. 2 is a flowchart of an electronic file decapsulation reading method according to an embodiment of the present invention, and as shown in fig. 2, the electronic file decapsulation reading method includes:
s201, downloading an electronic file package file to a target mobile device, wherein the electronic file package file is formed by uniformly packaging a plurality of electronic files, and the electronic files comprise attribute information and file contents of the electronic files. The attribute information of the electronic file comprises a file name, a file type, a file size and storage position information.
For example, the electronic file enclosure file may be downloaded to a designated location on the target mobile device.
Optionally, the electronic file decapsulation reading software that responds may be installed in advance on the target mobile device, and then the electronic file encapsulation body file is copied to the read target of the electronic file decapsulation reading software, where the directory is read, that is, the preset read path of the electronic file decapsulation reading software.
S202, reading the electronic file package files to obtain attribute information of each electronic file.
Opening electronic file decapsulation reading software, and acquiring attribute information and file contents of each electronic file included in an electronic file encapsulation file in a read target, namely reading a file name, a file type, a file size and storage structure information of a plurality of sub-files of the electronic file; then the user can browse the attribute information of each electronic file on the mobile device, and when the user needs to read the file content of a certain electronic file, the user clicks the electronic file to generate an electronic file content acquisition request.
Optionally, before reading the electronic file package file, the electronic file package file is also checked to determine whether the electronic file package file is damaged or part of the information is lost during transmission, so as to ensure the integrity of the information in the electronic file package file.
For example, when the attribute information of the electronic file is read, first byte information corresponding to each electronic file in the electronic file package file is read first, and the first byte information is decrypted to obtain the attribute information corresponding to each electronic file. The stored byte information is converted, recombined and restored into initial readable file information, and the readable file information comprises a text file, a picture file or a video file and the like.
S203, acquiring the file content of each electronic file according to the attribute information of each electronic file.
For example, according to the electronic file content obtaining request and the attribute information (including the storage location information) of the electronic file, the corresponding file content may be obtained, and then the corresponding file content may be displayed, so that the user may browse the file content of the electronic file.
Illustratively, when the file content of each electronic file is read, second byte information corresponding to the electronic file is acquired according to the attribute information of each electronic file, the second byte information is decrypted to obtain the file content corresponding to the electronic file, and the stored byte information corresponding to the file content is converted and recombined to restore the original readable file content, wherein the readable file content comprises a text file, a picture file or a video file. And finally, responding the decrypted file content to the corresponding acquisition request.
Optionally, after the electronic file package file is read to obtain the attribute information of each electronic file, unique identification processing is further performed on the file name, the file type, the file size, the storage structure information of a plurality of subfiles, and the like of each electronic file, that is, unique identification information is allocated to the attribute information of each electronic file, and then the unique identification information and the file information corresponding to each electronic file are written into the cache position in a key value pair manner. The method comprises the steps of obtaining unique identification information corresponding to the electronic files after obtaining file contents of the electronic files according to attribute information of the electronic files, namely simultaneously recording the unique identification information corresponding to the electronic files by the mobile equipment, and directly calling the file contents corresponding to the unique identification information according to the unique identification information corresponding to the electronic files when obtaining the electronic files next time so as to improve the efficiency of reading the file contents.
Therefore, by adopting the electronic file decapsulation reading method of the embodiment, the mobile device can read the related information of the electronic file without decoding the electronic file encapsulation file, thereby saving the storage space and the system resources.
