Storage device and method for loading extension function to different storage areas

Abstract

The invention discloses a storage device and a method for loading extension function to different storage areas. By the technical means that a main program judges whether an extension setting file is in the second storage area after a computer executes the main program stored in the first storage area and a target field is loaded after the target file corresponding to an extension setting projectrecorded in the extension setting file exits in the second storage area is judged, new data can be used under the condition that the data in the read-only areas are not updated, and the technical effect of reducing the burden of providing write-in data is achieved.

Description

technical field [0001] A storage device and method for loading extended functions, in particular to a storage device and method for loading extended functions into different storage areas. Background technique [0002] Storage media, according to whether the stored data can be overwritten, can be at least divided into two types: modifiable and non-modifiable data. The modifiable data storage media allows users to store non-specific data. [0003] In addition, according to the configuration inside and outside the computer, the storage device can be divided into two types: built-in type and external type. Among them, since the storage medium of the external storage device usually does not read and write data mechanically, it is stored in the external type. The data in the storage device is not easy to be damaged by machinery, so it is convenient for users to carry. Therefore, the data stored in the external storage device is usually non-specific data, so the external storage d...

Problems solved by technology

[0004] The most basic data in the external storage device can be modified arbitrarily, but when the manufacturer wishes to protect some data stored in the external storage medium so that the user cannot modify the data, generally the The external storage device is divided into two storage areas, and one of the storage areas is defined as a read-only area, and the data to be protected is written into the read-only area, so that users can only read and / or execute the protected data. data, but cannot modify protected data

[0005] However, in some cases, the protected data needs to be modified, such as data errors, data expansion, etc. Since users cannot modify the protected data, they cannot download or install new data to read-only In this way, if the user wants to use new data, he must ask the manufacturer to rewrite the new data into the storage area defined as a read-only area before using it, which will cause inconvenience to the user

[0006] In summary, it can be seen that there has been a problem in the prior art for a long time that new data needs to be rewritten into the storage area defined as a read-only area in the storage device before it can be used. Therefore, it is necessary to propose improved technical means to solve this problem. question
