Deletion of old patches

Deletion of old patches

Morning, Lucky here from South Africa

My patch folder is 13.2GB big, i have patches dating from 2014 up to date, my last patch is 9.4.0-SP-0.16.0 . What is the impact if i delete old patches from 2014 - 2017 to free up space on my server? Are the patches interdependent ?

Regards

Lucky
