I’m running OpenSUSE leap 15.5, When I was on the linux mint, I was using warpinator but using it on openSUSE is troublesome and I wish there was a linux version of blip but unfortunately there is not.
Simply install flatpak then install warpinator
I use kdeconnect with this script: https://github.com/Samueru-sama/kdeconnect-any-filemanager
Syncthing, KDE Connect
If you are on same network you can use
python3 -m http.server
It will launch a http server which will serve all the files in your computer.
