I am programing under windows, c++, mfc How can I know disk's format by path such as "c:\". Does windows provide such APIs?

推荐答案

您正在寻找Win32API函数:: GetVolumeInformation.

The Win32API function ::GetVolumeInformation is what you are looking for.

从MSDN:

GetVolumeInformation函数

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
);

示例:

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