I have a gaming laptop and a phone, both of which have USB 3.2 Gen 2 and Gen 1 ports. I also use a USB 4 Type-C cable. Now, recently, I have downloaded music files of over 300GB. If I transfer them one by one, it takes a lot of time. Today, I compressed the folder to a single zip file, and the transfer finished in less than 20m. Why is that so?


Syncthing
Self-hosted. Open source. Your data stays on your own devices. Creates a shared folder on your laptop and your phone. Move a file into that folder on your laptop, and syncthing pushes it to your phone.
I tried it but the connection speed is limited to my internet speeds for some unknown reason. Like, both my laptop and phone support Wi-Fi 6 but speeds are always around 22 MB/s max.
Which Wi-Fi standard does your router / access point support?
