Transfer files between partitions?
You may use some third party tools like Paragon-NTFS. It installs a driver on the Mac side that reads the NTFS partition of your Windows side. Some years ago I used the free "FUSE" drivers, but it seems to me, the development has stopped.

Another solution would be to use a USB thumb drive, which is FAT-formatted as a transfer volume. Both sides can read and write on that.
