Fun fact: If you need to “drop” to a device which you cannot or don’t want to install any software, if it has at least internet access, you can share files completely over the web using sharedrop.io. If there’s not even internet access, just use a simple http server (eg. install and enable apache, move files to /srv/http or use python -m http.server). If you have no software for that, you could use netcat.
