Hi the Snake
I have only found this API (old one was GetDiskFreeSpace)
Nothing with only 'GetDiskFreeExa' !
Hope it will be useful
SV
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, // 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
);
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 would 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.
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.
Remarks
Note that the values obtained by this function are of type ULARGE_INTEGER. Be
careful not to truncate these values to 32 bits.
Windows 95 OSR2: The GetDiskFreeSpaceEx function is available on Windows 95
systems beginning with OEM Service Release 2 (OSR2).
To determine whether GetDiskFreeSpaceEx is available, call the LoadLibrary or
LoadLibraryEx function to load the KERNEL32.DLL file, then call the
GetProcAddress function to obtain an address for GetDiskFreeSpaceEx. If
GetProcAddress fails, or if GetDiskFreeSpaceEx fails with the
ERROR_CALL_NOT_IMPLEMENTED code, use the GetDiskFreeSpace function instead of
GetDiskFreeSpaceEx.
QuickInfo
Windows NT: Requires version 4.0 or later.
Windows: Requires Windows 95 OSR2 or later.
Windows CE: Unsupported.
Header: Declared in winbase.h.
Import Library: Use kernel32.lib.
Unicode: Implemented as Unicode and ANSI versions on Windows NT.
