Yes, it is existing directory although Local Settings directory is 
hidden directory. I even tried changing temporary directory to c:\Temp 
(and I created that directory) but it didn't help the situation.

I tested it more and I found out that if I try to save modifications to 
existing file it fails in same way. So it looks like there is a problem 
with creation of temp file. But still, when I open existing remote file 
it can open it normally even though it uses temp file to transfer the 
file from remote host (or at least that's what I have understood how it 
works).

Ok. I'm not very familiar with Emacs and as I skimmed through the source 
code it looked like possible cause.
