[Andreas Masur]

Q: How to get information about a partition?

A:

#include <iostream>
#include <iomanip>

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)
{
  std::cout << "Volume name = " << szVolumeName << std::endl
            << "Serial number = " << dwSerialNumber << std::endl
            << "Max. filename length = " << dwMaxFileNameLength << std::endl
            << "File system flags = $" << std::hex << dwFileSystemFlags << std::endl
            << "File system name = " << szFileSystemName << std::endl;
}
