I bring my pdfs to pc first, rename them (sensibly), then download onto my iPad…lol. I did what you described for years before I developed a system. Cheers!Video. I got tired of managing storage every time I was getting ready to travel and wanted to download a bunch of movies to take with me.
The downside is with that much storage there's very little motivation to clean up Files so I have a ton of PDFs I've downloaded when researching things that aren't named sensibly and will probably never be opened again.
