Answer 1

GetDiskFreeSpace或GetDiskFreeSpaceEx

Answer 2

_int64  nFreeBytesAvailable;
_int64  nTotalNumberOfBytes;
_int64  nTotalNumberOfFreeBytes;
GetDiskFreeSpaceEx(strDisk,
(PULARGE_INTEGER)&nFreeBytesAvailable,
(PULARGE_INTEGER)&nTotalNumberOfBytes,
(PULARGE_INTEGER)&nTotalNumberOfFreeBytes); char Totabuf[MAX_PATH] = {0};
char Freebuf[MAX_PATH] = {0}; sprintf(Totabuf,"%.1f %s",(double)nTotalNumberOfBytes/1024/1024/1024,"GB");
sprintf(Freebuf,"%.2f %s",(double)nTotalNumberOfFreeBytes/1024/1024/1024,"GB");

Answer 3

    //获得磁盘空间信息，最后strsb字符串中的就是磁盘大小
    ULARGE_INTEGER FreeAv,TotalBytes,FreeBytes;
    if(GetDiskFreeSpaceEx("c:",&FreeAv,&TotalBytes,&FreeBytes))
    {
        //格式化信息
        CString strFreeBytes;
       char strsb[128];       _i64toa(TotalBytes.QuadPart, strsb, 10);  // 以10进制的方式将 64转成char
