Considering the size of projects, the checkpoints take up the majority of the allocated storage.
Is there a way to delete checkpoints?
If you archive a project. Delete from the dashboard and then reimport, does that remove the checkpoints?
Individual checkpoints cannot be deleted because they form a graph that
needs to remain intact. We are in the process of updating our general handling
of quotas to account for checkpoints. In the meantime, you can email us
a link to your project (support@playcanvas.com) and we will review/adjust usage
limits in your particular case.
