I don’t understand your problem. When you save your project, UE generates necessary files, including a “ProjectName.uproject” file. You can load the project by clicking on this file as well as from the Epic launcher. And what do you mean with “project things”?
Like the Britain said. It saves to \Documents\Unreal Projects by default. It should all be there. Also no worries on the bad English. If you think you spelled a word wrong just head over to ‘Google Translate’. Here is an example. You spelled guys as guyz. Our language doesn’t spell like it is written most of the time. And I’ve been learning Russian lately, so I’ve noticed how weird English actually is. Sorry for going on but I am terribly bored.
