Embodiment Construction

[0034] In the embodiment of the present invention, an identifier indicating whether to allow skipping is set in the description information. When extracting files, the file corresponding to the identifier that allows skipping may not be extracted. By improving the file packaging method, the extraction process is simplified and the processing efficiency is improved.

[0035] see figure 1 , the main method flow of file packaging in this embodiment is as follows:

[0036] Step 101: Obtain the file to be packaged;

[0037] Step 102: Generate description information for describing the file to be packaged, the description information includes an identifier indicating whether to allow skipping;

[0038] Step 103: Package the file to be packaged and the description information into a package file.

[0039] The location of description information generated by different packaging tools is different. The description information is located in the file entry item of the package file, an...

Abstract

The invention discloses a method for packing and extracting files, which is used for improving a file packing method, simplifying the file extraction process and improving processing efficiency. The method for packing files includes: acquiring a to-be-packed file, generating description information which is used for describing the to-be-packed file and comprises tags indicating whether to skip; and packing the to-be-packed file and the description information to form a package file. The invention further discloses a method for extracting files and a device for realizing the methods, wherein the method for extracting files corresponds to the method for packing the files.

Description

technical field [0001] The invention relates to the fields of electronic technology and data processing, in particular to a method and device for packing and extracting files. Background technique [0002] With the development of electronic and communication technology, especially the development of mobile Internet, reading is no longer limited to books. The emergence of mobile terminal devices such as mobile phones, tablet computers, and e-book readers has made mobile reading more and more popular. The content of reading has also become more and more abundant, not limited to text, but also includes many data contents such as images, audio and video, animations, and three-dimensional objects. [0003] Rich content promotes the development of the file structure, and a multi-file packaging method has emerged. File packaging refers to combining multiple files stored in a storage device into one file. The combined file is called a package file, and users can also extract requi...
