Hi,
If a folder has a file "a.b", I can't create a folder named "a.b" in the
same parent folder.
Here is how to recreate that in an "emacs -Q" session:
> emacs -Q &
C-x C-w C-a C-k ~/.emacs.d/test.el
M-: (make-directory "~/.emacs.d/test.el")
Doing so gave me the below error.
Unix allows have a file and a directory with the same name in the same
parent folder. I believe that the distinction between an existing file or
an existing directory is not being made here.
Debugger info:
Debugger entered--Lisp error: (file-already-exists "File exists"
"/home/kmodi/.emacs.d/test.el/")

As expected.

Not here, it doesn't:
eliz@fencepost:~/ttttttt$ touch a.b
eliz@fencepost:~/ttttttt$ ls
a.b
eliz@fencepost:~/ttttttt$ mkdir a.b
mkdir: cannot create directory `a.b': File exists
eliz@fencepost:~/ttttttt$
A directory is just a special kind of file on most filesystems, and
like a file, it has an entry in its parent directory. So there cannot
be a file and a directory with the same name, because there can be 2
identical entries in their parent directory.
This is not a bug in Emacs, this is a limitation of the underlying
filesystem to which Emacs heeds.
I'm closing this bug.

I meant "cannot be", of course. Sorry.
