Best cure for 4GB filesize limit of FAT32?

So basically I have a FAT32-formatted 16GB microSDHC in my N810's external card slot and I need to copy some stuff onto it which is larger than 4GB. Of course a fundamental limit of FAT32 is the max filesize is 4GB minus one byte. I'm sure I'm not the first to encounter this problem, what's the best way to get around it? I've considered reformatting the card with NTFS, but I'm not sure if the N810 will still have read/write access to it if I did that... thanks for any help. :)

EXT3

Or maybe ext2; I don't know how journaling and wearable sectors mix.

I really want to keep the whole thing to a single partition as it is if that's possible... also the instructions seem overly multifaceted for something this trivial, isn't there something like "format /dev/mmcblk1 -fs ext3"? Also if I use ext2/3 will I still be able to connect the N810 using the USB cable with WinXP?

You can create one big partition, but then you couldn't transfer stuff to a Windows computer. I would create a large ext[2/3] partition and a small fat partition, and use the fat partition as an intermediary to the ext partition and Windows computers.

To find software to do this on the tablet, search is your friend, or if you have a Linux computer, install gparted.

There's a number of possible arguments for both, but I think the convenience of ext3 (not having to fsck after every abrupt reboot) wins out slightly.

CyberCat, I haven't tried the ext2 driver for XP, but from what I've heard about it it should solve your interoperability problem.

I used an ext2 driver on Windows 10 years ago. It worked fine.
So I guess today's ext2/ext3 drivers for Windows are similarly good.
