This question reflects that it is possible to use a shared NTFS partition on a Ubuntu and Windows dualboot to keep and share your files between the two OSes. That question dates back to 2018, though, and that is a long time.
What is, to date, the best option to
- have a dualboot Windows Professional and Ubuntu
- have both OSes access and change the files
- neither OS should have files that the other OS doesn't have
Are there any innovations since 2018 that would make this easier? Exfat, for instance? What are the options to setup such dualboot (note dualboot, not Ubuntu on Windows WSL).
