Can you create separate files with Scribble?

Hello, I'm looking to buy an e-ereader which I could also use to take notes. The scribble app on PocketBooks (particularly the InkPad 3) has caught my eye, but I'm not entirely sure how it works. Can I go to a folder, open let's say Document1, edit and close it and then create a new Document2 that would be independent on the first one? Or if this isn't possible, could you recommend an e-reader that does this? (I have been looking into Onyx Poke Pro and the Android apps).
Thank you for any response.
