[xijuanhui]

各位大虾，在VC++ 如何得到硬盘已使用大小和未用大小 ，先谢了。。。 在线等...

//
// 以下求硬盘的剩余空间
DWORD dw=GetLogicalDriveStrings(0,NULL);
LPTSTR pAllDrivers=new char[dw];
::GetLogicalDriveStrings(dw,pAllDrivers);
LPTSTR pDriver=pAllDrivers;
char tempDriver[26];
memset(tempDriver,'\0',26);
DWORD DriverNum=0;

unsigned __int64 l_free=0;
while(pDriver[0]!=0)
{
if (GetDriveType(pDriver)==DRIVE_FIXED \
&& GetDriveType(pDriver)!=DRIVE_REMOVABLE)
{
tempDriver[DriverNum++]=*pDriver;
ULARGE_INTEGER i64FreeAmount;
ULARGE_INTEGER i64TotalAmount;
CString ls_drivename=*pDriver;//tempDriver[DriverNum-1]
ls_drivename+=_T(":\\");
::GetDiskFreeSpaceEx(ls_drivename, &i64FreeAmount, &i64TotalAmount, NULL);
//unsigned __int64 l_total=i64TotalAmount.QuadPart;
l_free+=i64FreeAmount.QuadPart;

}
pDriver=_tcschr(pDriver,0)+1;

}

这个问题我解决，现贴上答案。。 谢谢pomelowu(羽战士) (

请问：如何得到一个磁盘用户可以使用的第一个扇区号？

[pomelowu]

ULARGE_INTEGER i64FreeAmount;
ULARGE_INTEGER i64TotalAmount;

GetDiskFreeSpaceEx(_T("C:\\"), &i64FreeAmount, &i64TotalAmount, NULL);
