Which FS to choose for sharing in Mac OS X and Windows 7?

Question

macOS

I have a MacBook Air with Mac OS X 10.9 Mavericks and Windows 7 installed on 2 partitions of a 120 GB SSD roughly split in half. There was not enough space on the Mac partition and I decided to enable (by adding an entry to fstab) the built-in support for writing to NTFS in Mac OS X in order to use the free space of the Windows partition for the "dump" of photos and videos. But it wasn’t there: it turned out that NTFS support in Mac OS X is still not as stable as in Linux, there are problems, for example, downloading torrents to an NTFS partition using Transmission sometimes leads to terrible brakes that turn into a freeze, and those stored on it video files are often blocked by the system (they become translucent and nothing can be done with them in the Finder) and they have to be unlocked by changing the attributes manually through the terminal.
The conclusion I came to is that it is probably necessary to reduce the size of the Windows partition and create, as they say, "disk D:" on the freed space - a dedicated partition for user files. Naturally, I want it to be equally complete and seamlessly available in both operating systems.
In which file system should I format this partition?

Answer 1

In general, it is universal - this is ExFAT. But I would advise you to take a regular external hard drive for this purpose. Ideal solution for file storage. If desired, you can connect it to the router and give access to wifi.

Answer 2

120 gig laptop ssd, obviously not for downloading kints from torrents.
