Windows and OS X use different file systems natively. NTFS for Windows and HFS+ for OS X on the Mac. If you have a disk or partition set up with a file system that both operting systems can read and write to such as FAT32 then that can be used as a transfer point between the two operating system.
Another possible solution is that there is third party software that will allow Windows to read and write on HFS+, the Mac file system or OS X to read and write NTFS, the Windows file system.
I would not recommend FAT32 for inter-OS operability. Strange things happen when you have partition sizes of greater than 32 GB, and you cannot move files greater than 4 GB at all. The exFAT file system is a much better choice. It supports both large partitions and files for reads and writes in both OS X and Windows.
MacDrive current version has the best HFS access from Windows and costs more.
Their Pro version supports Apple RAID volumes which otherwise crash Windows.
Paragon has the best NTFS driver to write and mount NTFS drives.
This combo bundle if you want both HFS and NTFS , so you can write to any filesystem from either OS
