GetDiskFreeSpaceEx
The GetDiskFreeSpaceEx function obtains information about The amount of space available on a disk volume: The total amount of space, The total amount of free space, and The total amount of free space available to The user associated with The calling thread.

BOOL GetDiskFreeSpaceEx (
LPCTSTR lpDirectoryName,//a pointer to the directory name
PULARGE_INTEGER lpFreeBytesAvailableToCaller,//receives the number of bytes on
//disk available to the caller
PULARGE_INTEGER lpTotalNumberOfBytes,//receives the number of bytes on disk
PULARGE_INTEGER lpTotalNumberOfFreeBytes//receives the free bytes on disk
);

The Parameters
LpDirectoryName
Pointer to a null - terminated string that specifies a directory on the disk of interest. This string can be a UNC name. If This parameter is a UNC name, you must follow it with an additional backslash. For example, you order to specify \ \ MyServer \ MyShare as \ \ MyServer \ MyShare \.
If lpDirectoryName is NULL, the GetDiskFreeSpaceEx function obtains information about the disk that contains the current directory.

Note that lpDirectoryName does not have to specify the root directory on a disk. The function accepts any directory on the disk.

LpFreeBytesAvailableToCaller
Pointer to a variable to receive the total number of free bytes on the disk that are available to the user associated with the calling thread.
Windows NT 5.0 and later: If per - user quotas are in use, this value may be less than the total number of free bytes on the disk.

LpTotalNumberOfBytes
Pointer to a variable to receive the total number of bytes on the disk that are available to the user associated with the calling thread.
Windows NT 5.0 and later: If per - user quotas are in use, this value may be less than the total number of bytes on the disk.

LpTotalNumberOfFreeBytes
Pointer to a variable to receive the total number of free bytes on the disk.
This parameter can be NULL.

The Return Values
If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.
