Method for dumping data to mobile storage medium and extracting data therefrom

Abstract

A method for dumping data stored in a file originally to mobile medium includes: A, accessing multiple files assigned by parameters one by one, connecting and merging them into a byte stream in a memory named original stream, B, compressing the original stream to form another stream the original stream to form another stream named a memory stream C, computing the byte add-up sum, D, writing the stored interface mark, memory stream length, original stream length, byte add-up sum and memory stream content in the mobile medium. The invention also discloses a method for picking up related data from the mobile medium and recovering it to file.

Description

field of invention [0001] The core of the present invention is a method for dumping data onto a removable storage medium and extracting data therefrom. The removable storage medium mainly refers to a floppy disk, a U disk, a removable hard disk, etc., wherein the 3.25-inch floppy disk (capacity 1.44M) is Mainstream small amount of data frequently reported storage media. Background technique [0002] The dumping, transmission, extraction, and reuse of data are data exchange activities, and the transfer through mobile storage media is realized by traditional and simple technology. The construction of computer network provides a better platform for the realization of data exchange, but due to the following reasons, the scheme of using mobile media to transmit data still has sufficient application basis and broad application stage for a period of time. [0003] One of the reasons: the deployment of the computer network is always in accordance with a certain plan, restricted by ...

Problems solved by technology

[0012] If you do not access data in the form of files, you cannot use the file processing functions provided by the operating system, and you need to use a relatively low-level storage medium for direct access. This method has obvious disadvantages, that is, poor compatibility, which is manifested in two aspects: The first is that a specific program can only access specific data. On the contrary, to access specific data, a specific program needs to be written; the second is that the underlying media access technologies provided by different operating systems are not the same, and cannot be accessed like files. , to implement in a unified way, at least it needs to be implemented separately for various mainstream operating systems

Due to the existence of this defect, this technology is not suitable for use in general-purpose products, such as software tools such as word processing (Word / WPS, etc.), graphics and image processing (CorelDraw / PhotoShop, etc.); However, I found that this technology has application value, because the industry software is just a specific program, and the data it processes is also a specific data. It does not deliberately pursue compatibility, and the higher the data security, the better. , that is to say, there is a reason for adopting the technical solution involved in the present invention; and another poorly compatible aspect of this technology is the concrete realization of the core idea of ​​the present invention
