如何知道某个磁盘格式（是FAT32或NTFS）(How to know a certain disk

我的窗户，C ++编程下，MFC我怎么能知道通过路径磁盘的格式，如“C：\”。窗户是否提供这样的API？

Answer 1:

该Win32API函数:: GetVolumeInformation是你在找什么。

从MSDN：

GetVolumeInformation功能

BOOL WINAPI GetVolumeInformation(
    __in_opt   LPCTSTR lpRootPathName,
    __out      LPTSTR lpVolumeNameBuffer,
    __in       DWORD nVolumeNameSize,
    __out_opt  LPDWORD lpVolumeSerialNumber,
    __out_opt  LPDWORD lpMaximumComponentLength,
    __out_opt  LPDWORD lpFileSystemFlags,
    __out      LPTSTR lpFileSystemNameBuffer, // Here
    __in       DWORD nFileSystemNameSize
);

例：

TCHAR fs [MAX_PATH+1];
::GetVolumeInformation(_T("C:\\"), NULL, 0, NULL, NULL, NULL, &fs, MAX_PATH+1);
// Result is in (TCHAR*) fs

Answer 2:

是的，它是GetVolumeInformation。

TCHAR szVolumeName[100]    = "";
TCHAR szFileSystemName[10] = "";
DWORD dwSerialNumber       = 0;
DWORD dwMaxFileNameLength  = 0;
DWORD dwFileSystemFlags    = 0;

if(::GetVolumeInformation("c:\\",
                            szVolumeName,
                            sizeof(szVolumeName),
                            &dwSerialNumber,
                            &dwMaxFileNameLength,
                            &dwFileSystemFlags,
                            szFileSystemName,
                            sizeof(szFileSystemName)) == TRUE)
  {
    cout << "Volume name = " << szVolumeName << endl
         << "Serial number = " << dwSerialNumber << endl
         << "Max. filename length = " << dwMaxFileNameLength
         << endl
         << "File system flags = $" << hex << dwFileSystemFlags
         << endl
         << "File system name = " << szFileSystemName << endl;
  }
