trouble copying large (12Gb) file from HD to 32Gb flash drive

[Morbius1]

One of the strange ironies about OSX is that it does allow write access to NTFS partitions natively - it's just implemented in a very strange way:

You could also us exfat which is designed for flash drives, has no file size limit that you'll ever reach & works in Windows & Osx (recent versions
Support for read, write & formatting a drive is available in 13.04/13.10 or thru a ppa for earlier Ubuntu releases
(packages in 13.04/13.10 are -
exfat-fuse
exfat-utils

formatting a drive to exfat in Ubuntu is quite easy, & 13.04/13.10 need no help mounting, eariler may need to be manually done.
No sense going further if not interested, otherwise this page gives basics

Note that 13.04/13.10 don't need the ppa nor any 'help' mounting, exfat drives are recognized & mounted like any other supported Fs

There are other options for reading (only) ext4 in Windows. Here are some, including Ext2Fsd referred to by Varundera.

Just format it as NTFS. It doesn't matter if it's ready-only on Mac. What matter is you'll be able to copy the file from your flash drive to other OSes (including Mac).
Unless you're planning to modify something on that 12Gb file from your flash drive.

With NTFS, you don't need to install additional software on your windows OS to copy the file from your flash drive.
I'm not sure though if Windows XP with FAT32 is able to read NTFS formatted flash drive or not.
