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.
