* Question
What is the file system structure of SCOS? |
* Answer
1) SCOS has two layers of files MF and EF. Since it is dedicated to one card, the DF file is no longer set.
(2) There are three internal basic files of SC()S: the SF storing the password, the KF storing the key, and the AF storing the system information.The internal basic files are for COS access only and have a transparent structure. 4) SCOS accesses the file with a unique identifier (2 bytes). (5) The EF file consists of two parts: the file header and the file body. The SSCO uses the file header and the file body to separate the opposite storage methods, that is, the file headers are grouped together andThe E2PROM minimum address (0000) starts to be stored; the file body is also put together and stored from the E2PROM maximum address. |
