I’ve been a paying user of Filen for many years now, and while it’s security is top notch their speeds are insanely slow. Like ludicrously comically slow. I’ve sent links to people to download stuff from my storage there and every single person I have ever shared a link with has said it was so slow that it either timed out or they just gave up. So I basically only use it for the most sensitive and important documents now. I would seriously consider other options for any larger files.

I’ve had the same experience with KDE connect. I’ve been using linux since 1998 and still can’t seem to get KDE connect to actually work properly. However, on the other hand local send works perfectly every…single…time… with literally zero effort. I mainly use it to quickly send files back and forth between my PC and phone.
