Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] see figure 1 , figure 1 Flow chart of the method provided for this application. Such as figure 1 As shown, the method includes:

[0028] Step 101, when adding a custom file to the image file, determine the size L of a directory record (Directory Record) corresponding to the custom file.

[0029] The customized files here include but are not limited to pre-configured files and files customized for requirements.

[0030] The following will focus on describing the structure of Directory Record, so I won't go into details here.

[0031] Step 102, determine whether there is a blank area with a size greater than or equal to L in the Directory Record structure storage area corresponding to the image file, and if so, perform step 103.

Abstract

A method and apparatus for image file processing; when a custom file is added to an image file, if there is empty space in a storage area of a directory record structure corresponding to the image file which satisfies the following conditions: being equal to or greater than a size (L) of the directory record corresponding to the custom file, then decompression and recompression of the image file is not carried out, and the custom file is instead directly added to a set position within the image file, and the directory record corresponding to the custom file is recorded in the empty space in the storage area of the directory record structure which is equal to or greater than L in size, on the basis of the set position.

Description

technical field [0001] The present application relates to data processing technology, in particular to a method and device for image file processing. Background technique [0002] Due to the development trend of Internet big data, it is often necessary to automatically install the operating system (OS: Operation System) on hundreds of servers. During the OS installation process, there is often a need to customize the installed OS, such as adding an installation package of a required program so that the required program can be automatically installed during the OS installation. [0003] However, in order to realize the above customization requirements, it is necessary to add a file corresponding to the above customization requirements to an image file (also called an ISO image file) in the OS. At present, the specific process of adding files to the image file in the OS is as follows: first decompress the entire image file, then add files to be added to the image file, and th...
