On Windows I wrote e.bat. Usually at Total Commander or Far file manager 
  I find file by cursor, type e<space><CTRL+Enter> and emacs popup with 
opened file (if it already not opened I get error and quickly type 
<Enter>). As for me `--no-wait' very useful not needed type C-x # and I 
can come back to the opened file later typing C-x b.
