CH376S如何更改多级文件夹的时间？

CH376FileOpen();和CH376FileOpenPath();
是不是只能打开实际的文件，而对文件夹无效？
更改文件夹而非文件的修改时间应如何操作？




UINT8SetDirRevisetime( PUINT8 iFileName, UINT16 iReviseDate, UINT16 iReviseTime )
{
/* Time = (Hour<<11) + (Minute<<5) + (Second>>1) */
/* Date = ((Year-1980)<<9) + (Month<<5) + Day */
//修改文件夹修改时间
//2020.9.24


UINT8s;
u8 buf[64];
strcpy(buf,iFileName);
s = CH376FileOpen( buf );  /* 打开文件 */
//s = CH376FileOpenPath( iFileName );
if ( s == USB_INT_SUCCESS ) {
/* 文件读写操作等... */
s = CH376DirInfoRead( );  /* 读取当前文件的目录信息FAT_DIR_INFO,将相关数据调到内存中 */
if ( s == USB_INT_SUCCESS ) {
buf[0] = (UINT8)iReviseTime;  /* 文件创建的时间,低8位在前 */
buf[1] = (UINT8)(iReviseTime>>8);  /* 文件创建的时间,高8位在后 */
CH376WriteOfsBlock( buf, STRUCT_OFFSET( FAT_DIR_INFO, DIR_WrtTime ), 2 );
buf[0] = (UINT8)iReviseDate;  /* 文件创建的日期,低8位在前 */
buf[1] = (UINT8)(iReviseDate>>8);  /* 文件创建的日期,高8位在后 */
CH376WriteOfsBlock( buf, STRUCT_OFFSET( FAT_DIR_INFO, DIR_WrtDate ), 2 );
s = CH376DirInfoSave( );  /* 保存文件的目录信息 */
if ( s == USB_INT_SUCCESS ) {  /* 成功修改并保存 */
/* 文件读写操作等... */
}
}
CH376FileClose( FALSE );  /* 关闭文件 */
}
return( s );
