Why is copy/paste of Library assets done so badly?

Windows does copy/paste correctly.  When you copy/paste something in windows, it changes a file: "apple.txt" to "Copy of apple.txt"

If you copy again, it gives you "Copy(2) of apple.txt"

Windows doesn't create an entirely new directory structure to put "apple.txt" somewhere.

Besides the obvious problem of having to constantly delete directory structures in Flash Professional CC when copying stuff, it also breaks the functionality of files.

Let me give an example how copy/pasting in library simply does not work because of this:

I have a directory:

_Bri

   -Bitmaps

   -Movieclips

In Bri/Bitmaps I have the raw .pngs

in Movieclips I have the symbols/movieclips built from them

One movieclip might be called:

PUNCHEAST

It draws from 4 bitmaps in bri/bitmaps

Now where it breaks down is here:

I want to copy PUNCHEAST to make ATTACKEAST using the same .pngs

So I copy PUNCHEAST and paste PUNCHEAST

The directory structure now looks like this:

_Bri

  _Bri

       -Bitmaps

          puncheast1.png

       -Movieclips

          -PUNCHEAST

-Bitmaps

    puncheast1.png

       -Movieclips

          -PUNCHEAST

As you can see, it copied not only the MOVIECLIP container PUNCHEAST, but also all the .pngs too!

Now when I rename PUNCHEAST in the redundant directory to ATTACKEAST, copy it over, and then delete the redundant bitmaps what happens is it ends up being a blank animation:

_Bri

-Bitmaps

    puncheast1.png

       -Movieclips

-Movieclips

  -PUNCHEAST

  -ATTACKEAST(now is blank because it was referencing the copied .png)

--------------------------------------------------

All this would work fine if instead of copying the entire directory structure, it would have done this when pasting:

_Bri

  -Bitmaps

    puncheast1.png

       -Movieclips

  -PUNCHEAST

  -Copy of PUNCHEAST

That is all.
