只要大多数应用程序继续使用软盘图标，大多数用户就会熟悉它，您的应用程序也会从熟悉的界面中受益。在经济学中，这被称为网络外部性。

正如其他人所说，保留软盘图标，不要担心。在我住的地方，这是火车过马路的警告标志:

大约有50年没有蒸汽机车了，但每个人都知道这是火车的标志。同样地，50年后，当你的文件存储在轨道上的谷歌服务器上时，每个人都会知道软盘是保存数据的象征。

老式科幻电影里的那种磁带驱动器怎么样?

这个图标将是永恒的!

如果您使用软盘图标，使用您的应用程序的用户将发现它更有用。为了一致性，如果能让你感觉好点。它是无处不在的。

It's funny that I found this discussion because I was looking for a standard 'save' icon I could download to replace the 'new and improved' icon that UtlraEdit started using and which was too difficult to pick out on the toolbar. Yes, it is outdated, but everybody recognizes the 3.5" floppy disk image as representing 'save'! Yes, programmers should not be doing things because 'that's the way it's always been done' but icons are language and not methodology. Don't invent a new word just because it would be cool unless your aim is to hide what you are saying from the previous generations.
