The send-to menu in Windows is useful for opening a file with an application other than the one you usually use. For example, you have a text file. You know it is a plain text file, but the name ends in something other than txt. So you open Notepad or some other editor that can read and write text files.
Not impossible to do, but it can be tedious. You open Notepad, you click File/Open, you then have to navigate to the appropriate directory and tell Notepad that you want to work with files other than plain text. Why go to all that trouble?
