import core.sys.windows.winbase : GetDiskFreeSpaceEx;

Use wstring's and .ptr them and everything should work.

Hi Rikki,

    Wouldn't this be easy to use with std.process: execute package 
and calling wmic.exe, the only problem is i am not sure hot to 
get the out put without the headings(Caption  FreeSpace,Size) any 
help on same is much appreciated.

import std.process: execute;
import std.stdio : writeln;

void main () {
version(Windows) {
auto result = execute(["wmic.exe", "logicaldisk", "get", 
"size,freespace,caption"]);
writeln(result.output);
}
}
Output :
Caption  FreeSpace    Size
C:       19702837248  180043665408
H:       85580382208  824633720832

Don't call external processes when you can call a function. 
Running another process is overhead and not reliable.

writeln(result.output[38..$]);
