This is full the path to the file, starting at the MF.

This is the file type. It can be one of SC_FILE_TYPE_DF, SC_FILE_TYPE_WORKING_EF, or SC_FILE_TYPE_INTERNAL_EF. The latter is used by some cards only, and you normally shouldn´t have to deal with these files.

For elementary files (EFs), this field describes the file´s structure. It can be one of:

gives the file´s size in bytes.

gives the file´s ID, as a 16-bit number.

For record structured files, record_sount specifies the number of records in the file. For files with fixed length records, record_length contains the record length.
