As noted above, we have a checklist that will help you get your settings, templates, backups and so forth all located, for easy transfer / backup with a drive.
As for your projects, well we can’t help with that too much since it is up to you to organise them and choose where to save them. You might want to use File Explorer to search for folders ending in “.scriv” though, as that is what a project folder will be named like, with that whole folder needing to be copied.
