FatFS中的FILINFO介绍

当调用FatFS中的f_readdir函数返回FILINFO值的时候，大家如果直接看FILINFO里面的值可能看不懂。因为里面的值需要大家转换一下，FILINFO的具体格式如下：

The FILINFO structure holds a file information returned by f_stat and f_readdir function.

typedef struct {

    DWORD fsize;      /* File size */

    WORD  fdate;      /* Last modified date */

    WORD  ftime;      /* Last modified time */

    BYTE  fattrib;    /* Attribute */

    TCHAR fname[13];  /* Short file name (8.3 format) */

#if _USE_LFN

    TCHAR* lfname;    /* Pointer to the LFN buffer */

    int   lfsize;     /* Size of the LFN buffer in unit of TCHAR */

#endif

} FILINFO;

Members

fsize

Indicates size of the file in unit of byte. Always zero for directories.

fdate

Indicates the date that the file was modified or the directory was created.

bit15:9

Year origin from 1980 (0..127)

bit8:5

Month (1..12)

bit4:0

Day (1..31)

ftime

Indicates the time that the file was modified or the directory was created.

bit15:11

Hour (0..23)

bit10:5

Minute (0..59)

bit4:0

Second / 2 (0..29)

fattrib

Indicates the file/directory attribute in combination of AM_DIR, AM_RDO, AM_HID, AM_SYS and AM_ARC.

fname[]

Indicates the file/directory name in 8.3 format null-terminated string. It is always returnd with upper case on non-LFN configuration but it can be returned with lower case on LFN configuration.

lfname    长文件名：存放地址

Pointer to the LFN buffer to store the read LFN. This member must be initialized by application prior to use this structure. Not available on non-LFN configuration.

lfsize

Size of the LFN buffer in unit of TCHAR. This member must be initialized by application prior to use this structure. Not available on non-LFN configuration.
