That's probably the right place. You can confirm in the R Edit|GUI
preferences dialog: it defaults to trying to save or load from the same
place it would look for .Rprofile.

You can put it in double quotes. It's really your editor doing this;
most reasonable editors (but not the ones that come with Windows) are
configurable to never add the extension.
Another change to Windows defaults that's essential to maintain sanity
is to tell it to display full filenames, not to hide the .txt in the
first place. You do this in an Explorer window by clicking on
"Tools|Folder options...|View|Hide extensions for known file types"
(where each of the 4 components in that path is a different kind of
interface element. I love the rich Windows user interface!)
