Question regarding updater
 

O kso I know you say to delete the old folder before you would download and manually install a new version. How does the updater address this? Does it delete the file before updating it? Does it remove the files that are no longer needed? Should we manually download the latest version then only run the updater afterwards?

The updater never deletes any files because it cannot know whether they are there on purpose (maybe you installed another mod) or not.
