I think correctly you would call the character that you need to use on
Windows a backslash (\) and that's the one you need to escape, because
it is the escape character in Mathematica. On other systems you will
need other characters for separating directories in pathes, which one is
 held in the variable $PathnameSeparator. AFAIK on Windows in many
places within Mathematica a single slash (/) will also work as a
pathname separator in filenames. Probably you shouldn't rely on that but
it's more convenient than the double backslash sometimes.

An even better approach is to construct the filename with the function
ToFileName, starting with one of the predefined directory variables you
can find with

Information["$*Directory*"]
