Chapter 8: Break through short names and solve long names: Break through 8.3 short name restrictions and fully implement long file names

Long file name (LFN) is the opposite of short file name (SFN). It allows the file name to contain more characters and express richer meanings.

The naming method is also more flexible.

struct FileInfo

{

UINT8 have_lfn; //Used to indicate whether this file has a long name

UINT16 longname[MAX_LFN_LEN+1]; //Buffer for storing long name UNI string

};

The file name is abcdefghijklmnopqrstuvwxyz.txt
