The icon to save any file is still representing a floppy disk 3,5''. This device is out of use for decades. I propose to replace this icon by an another which could be more self explaining.
The "floppy disk" does no longer work as a representation of a physical storage medium, but has become a widely understood symbol for "save". There have been some researches on this topic. A start might be at https://user-prompt.com/de/find-the-best-icon-for-save-as/ https://user-prompt.com/de/how-designers-think-about-save-as/ https://user-prompt.com/de/about-antiquated-metaphors-in-icons/ For me this bug report is a "wontfix".
