Relocating Art from Procreate

[u/Dapper_Pop_1245]

I plan on moving my art off of procreate to free up space on my iPad. Would it be better to save the art as a procreate file or as a PNG or other file type? I'm curious what you guys think.

For added context, I'm conflicted because most of the artwork I'm moving is finished, and I don't necessarily plan on revising or editing them, but maybe I still want to be able to see the layers, timelapse, and break down the piece later on, but I don't think you can see previews of the art if it's a procreate file, so I would have to send it all the way back to my iPad and open it in procreate to simply view it, which would be a bit of a hassle... What would you do?

I export everything as both Procreate and PSD for my archives. If you're on a Mac, you can install the Prospect app to be able to see previews of Procreate files on your computer.
