Ever hear of the "sneaker net"? That was real popular a few decades ago. After that came bulletin board systems and dial-up connections. Some of these still operate. That's where I downloaded files in the 80s and early 90s. There is also ad hoc networking using your cellphones or network routers. With the router, you would need to be close enough to a neighboring router to connect to it. Cellphones can also connect to each other without the cellphone system or cell towers if they are close enough.
MicroSD cards are really compact. You can theoretically fit many TBs of them in a single Altoids tin. Just make sure you have the SD adapter and a USB adapter. I bought a bunch of microSD cards so I can carry multitudes of files with me. I can swap them out in my little Fire 7 that I got a few years ago for $29.99. Amazing price for that much info convenience. I can show people a lot of stuff quickly on that thing. Also, it can slide into a shirt pocket.

There are more ways that this.
Got a sack full of them.
