Needing FTP Software with editing and hides system files?
I believe that Transmit from Panic Software will meet all of your needs. 

There is a menu option that toggles the visibility of dot (.*) files. View menu (Hide/Show) Invisible Files.

To edit a remote file in Word, right click on the remote file and select "Open With..." and select Word from the context menu to edit the file. Edit and Save the file within Word and the file will be uploaded as soon as the save completes. There is nothing else to set up.

I usually use this method with BBEdit and Text files, but I tested and it works with Word files.
