Yes.  As a software developer, we sometimes have to send .exe's and
..dll's to people via e-mail, and packing them in password-protected .zip
files is not enough to get those files through academic and corporate
(and, increasingly, sadly, their out-sourced email choice of Microsoft's
outlook.com) mail handling systems.  We have to mung the file extensions
before sending them via .zip, or use .rar.

I have what is probably an older version of 7-zip, and I don't see the
option to encrypt (or alter, or hide) file-names or file extensions when
packing .zip archives.

Winrar (and the .rar format) has this ability.
