Suppress or replace All files on File open?

[Harm10]

I want either to replace filetype All files with my own description (in my language) or to suppress the All files filetype being added to the list of filetypes active. How can I do that? I have tried adding ['.', 'Really everything!'] to the list which gets added but All files option is still there.

Can I get a response please?
