How to properly remove the CUDAResources paclet?

Question

I have Mathematica 8.0.0.0 installed on my Mac, and while I tried to see what it could do with CUDA, it downloaded a large directory (~1 GB) named CUDAResources-OSX-8.0.0.8 in ~/Library/Mathematica/Paclets/Repository/. However, after the download, I tried to see what it would give but CUDAQ[] returns False on my system. Seeing that CUDA's not going to be useful on this machine, how can I reclaim this disk space? In other words, how to get rid of this downloaded data?

Answer 1

Just check: CUDAResourcesUninstall[]

Answer 2

This is somewhat of a long comment on VLC’s answer…

Okay, now I know why CUDAResourcesUninstall[] didn't do the job, though I still don't know how to work around it. Due to updating from 8.0.0.0 to 8.0.4.0 recently, it turns out that the new version of Mma installs a new version of the paclet, named CUDAResources-OSX-8.0.4.1. That's the one that CUDAResourcesUninstall[] then uninstalls. But the older (now useless) 880 MB directory is left in place, unfortunately.

Given that I don't know how to properly remove this stuff, I ended up blasting the entire content of ~/Library/Mathematica/Paclets/Repository (most of which was probably related to the older Mma version). I hope Mma will not have me pay for this. I still don't understand why a minor version upgrade ends up leaving around 1 GB of old stuff on one's account…
