I upgraded a dev site to EE3 and my snippets are now placed into two folders, _global_partials and _partials. I can't seem to find the difference on what these folders are. At first I thought it may have something to do with template variables but adding a new template variable just puts it in a folder called _variables. EE3 docs don't seem to have what the difference between the two folders are. Has anyone figured out the difference?
