Something like:

auto mSize () {
	string FFs = "C:\\Temp\\BACKUP";
	
    return dirEntries(FFs, SpanMode.shallow)
    .filter!(a => a.isDir)
    .map!(a => tuple(a.name, 
a.dirEntries(SpanMode.depth).filter!(a=>a.isFile).map!(a => 
a.size).sum))
    .filter!(a => a[1] > 1024*1024*30)
    .map!(a => tuple(a[0], a[1].to!string))
    .array;
}
