You have to delete them, I think you can do it via the Raspbmc addon, however you still have the archive in /home/pi/.
You don´t need them if you don´t use them, and if you need to debug and install an old build you can just come back here and install it again.

Fastest way to delete them is probably to do it via SSH.

Archive:

Code:

rm /home/pi/name_of_build.tar.gz

Build:

Code:

sudo rm -R /home/pi/.upgrade/name_of_build
