Hi Andrea,

   I test your code, initially it error ed out stating "patch does 
not exist", the reason for this error is that the length of the 
path is more than 256 , so added the UNC path to the code as 
below.

auto mSize () {
string FFs = "C:\Temp\BACKUP";
ulong SGb = 1024 * 1024;
int SizeDir = 10;

return Array!(Tuple!(string,real))(
  dirEntries(join(["\\\\?\\", 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] >  (SGb * SizeDir))
  .map!(a => tuple(a[0], ((a[1].to!real)/ SGb ))));
}

The output of the code is as below
\\?\C:\Temp\BACKUP\dir1                                 34.90
\\?\C:\Temp\BACKUP\dir2                                 36.18

So how do we print the output without UNC path
C:\Temp\BACKUP\dir1                                 34.90
C:\Temp\BACKUP\dir2                                 36.18
