I have a hosting account which has a maximum of 250 MB total space. I have installed Drupal 8 and I'm using the bootstrap theme and already my host has warned me that I am nearing my limit for file space. This is only going to be a small site, so it really shouldn't need that much space. Is there any way I can clear up space by deleting unused files in the Drupal 8 system?
For instance, is it possible for me to disable themes and then delete those folders? And also to uninstall core modules that I'm not using and delete those folders as well? Or are there any other ways I can clear up space?
If it is not possible then I will probably switch to using Drupal 7, which would be my 2nd option.
