There is no shortage of apps to backup contacts, photos, calendar, videos, etc from Android to PC.
I am looking for one (gratis) that allows me access to the full file system - in both directions.
Beyond that, I don't care e.g whether it uses USB cable, WiFi, BlueTooth. A slight bonus might be searching for file name/contents, but I can achieve that with other tools, so it is just a convenience, not a requirement.
