import std.range : empty;
version (Posix)  assert(driveName("c:/foo").empty);
version (Windows)
{
    assert(driveName(`dir\file`).empty);
    writeln(driveName(`d:file`)); // "d:"
    writeln(driveName(`d:\file`)); // "d:"
    writeln(driveName("d:")); // "d:"
    writeln(driveName(`\\server\share\file`)); // `\\server\share`
    writeln(driveName(`\\server\share\`)); // `\\server\share`
    writeln(driveName(`\\server\share`)); // `\\server\share`

    static assert(driveName(`d:\file`) == "d:");
