The best part is it works with Android as well. Whenever I turn my computer on, all my photos on my phone sync to my computer to a folder that gets regularly backed up (using Vorta which is an excellent and easy to use open source backup program for Windows, Linux, and Mac)
Try Material Files file manager. It’s the best file manager I’ve used, connects to remote servers, and is open source
