You can set the title of your Emacs window to the name of the file being edited. Add the following code to your .emacs file. Note, I run Emacs from within Cygwin where the HOME environment variable uses double backslashes as path separators, and the buffer-file-name uses slashes as path separators. The regular expression replacement below performs the conversion from backslashes to slashes.
(replace-regexp-in-string "\\\\" "/" (getenv "HOME")) "~"
(concat (file-name-directory buffer-file-name) "%b"))
