I'd recommend that we make it look like this:

Your proposal goes into the right direction but the black motive in front of the folder is way to small to be recognized in the file explorer. In addition the black color does not fit onto the folder icon. So this is why I'd suggest to make it look as shown above.

Your idea looks much better so please add this.
