Arduino Due with Atmel Studio

Hello to everybody.

I have an Arduino Due board and I would like to program it using Atmel Studio. I have read that the bootloader is permanently in the ROM of the SAM3X micro, and it will not be flashed.

Another doubt I have is how to find the compiler. In this tutorial:

I have seen that the compiler path is:

C:\Users<USER>\AppData\Local\Arduino15\packages\arduino\tools\bossac\1.6.1-arduino/bossac.exe

But I have not found it. I use Windows 8.1.

Has anybody configured the Arduino Due for Atmel Studio?

Thanks in advance.

I have seen that the mentioned folder is hidden:
