In recent, I'm using the Alphafold function in Chimera X daily version.

I have 4 questions.

First, if I use Alphafold to predict my important project data, is it keep secure privately?

I want to keep my data secret. It shouldn't be open to anybody without me. 

Second, when I using Alphafold in ChimeraX, I faced some error messages that mean 'Not enough disk volume. please remove past data.'. I'm not familiar with google colab...how can I manage the disk to remove past data or expand disk volume? 

Third, how can I improve the speed of alphafold prediction? ChimeraX shows some resources like ram, disk. 

fourth, I want to operate simultaneously Alphafold prediction to predict 2 or more structures. Is it possible? 

If there need some pay to improve the second, third, fourth question, please let me know methods.

Many thanks.
