Abstract

The invention discloses a method and device for storing a COS (chip operating system) file, wherein the method comprises: acquiring a command to store a target COS file that includes a header and a file body; storing the header of the target COS file to a node of a corresponding header list, and storing the header list to a first storage region, with the node of the header list including one or more sub-nodes, and each sub-node corresponding to a header of one COD file; storing the file body in corresponding position in a second storage region. The method allows a header and a file body to be saved in different positions in a storage region so that it is possible to centrally manage headers, using headers containing file summary information to perform file retrieval, query and other common operations is facilitated, and system efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of file storage, in particular to a method and device for storing COS files. Background technique [0002] With the development of microelectronics technology, various smart cards begin to enter people's lives. Whether it is a mobile phone card, bank card, water card, electricity card, social security card, access control card or even an ID card, they are all smart cards in different industries. Since smart cards are widely used and their application environments vary greatly, their user data are different, and smart cards need to allocate appropriate user space to store these business data. [0003] Due to the slow processing speed and small storage space of the early smart cards, general business data are directly written into the storage area. However, the card application directly operates the storage area, which is likely to cause confusion of data in the storage area and does not conform to the trend...
