Is there a way of storing files in Scrivener

I mean, like a pdf or a powerpoint file or other files. Not converted. Scrivener is perfect for my need, I only need a program that can save all of my files in one place.

Sure, you can drag any type of file at all into the Binder, just make sure to do so in an area outside of the special “Draft” folder. PDF files in particular will be displayed in the editor. File types that Scrivener cannot directly read will either display an icon, so you can load them easily in their original program (PowerPoint files would fall under that category), or they will display a preview if the OS knows how to display them (we use the same technology there that you would see if you use Quick Look in Finder).
