remove uses DeleteFile, but MSDN says
To remove an empty directory, use the RemoveDirectory function.

so remove probably won't work on directories.

Does not work. I modified the relevant block like this:

  if (exists(BlankDirToDelete))
  {
    string SafeToBeDeleted = buildPath(`\\?\`, SearchPath, baseName(BlankDirToDelete));
    writefln(`"%s"`, SafeToBeDeleted);
    try
      remove(SafeToBeDeleted);
    catch (FileException e)
      writeln(e.msg);
    try
      remove(`\\?\` ~ SafeToBeDeleted);
    catch (FileException e)
      writeln(e.msg);
  }

The result?

"d:\ "
d:\ : Access denied.
\\?\d:\ : Access denied.

This happens even while executing the prompt as administrator, so it's not a problem of file privileges. Note that from the Windows explorer I am also having problems renaming or deleting the problematic directory, however with something else like Total Commander, I can both rename and delete with no issues.

You are correct, so I made a few test using rmdir() with a blank for directory name and now I get:

d:\ : Directory is not empty.

However, the diretory is certainly empty. Go figure!

Note that in Windows I cannot create a directoy with a blank name from D either, so in order to test this, I have to create it elsewhere.

Update: the combination of both your suggestions worked:

  if (exists(BlankDirToDelete))
  {
    try
      rmdir(`\\?\` ~ BlankDirToDelete);
    catch (FileException e)
      writeln(e.msg);
  }

Thanks! Now I just have to find out why the block of the file extensions is failing.
