FUSION 360 POST PROCESSOR sorry if I'm beating an old rock

Does FUSION 360 POST PROCESSOR download to my computer or do I download to my arcdroid


Here’s the thread

After dowmloading the post to your computer you have to import it in Fusion 360.
If you go to manage in Fusion, you can choose the post library. There you can import the post file you have downloaded.
When setting up a ‘new setup’ in the ‘macgining’ area you select the Arcdroid post.
