The best file system to access from all operating systems

Question

macOS

I want to install MacOS X, Ubuntu 10.10 and Windows 7 on iMac at the same time (let's do without holivors about reasons and expediency). I think to make not only a disk partition for each system, but also a separate large partition with work and personal files, access to which will be from under all operating systems. Question: what file system should be used for this large partition, which one is best supported by all systems at once?

Answer 1

It's been grinded many times already.
NTFS with ntfs-3g driver on other OSes. The most stable option.
The weak link is Win.

Answer 2

Look at UDF if Linux is modern and Win vista / 7 will be.

Answer 4

NTFS. The worst thing will be in Linux, and you can put firewood from paragon software on the poppy - the poppy will work with ntfs no worse than Windows.

Answer 5

FAT - everything will work correctly with it. Probably UDF, did not use it.
The option with ntfs has the right to life, only ntfs-3g is a slow thing on large amounts of data.
