Storing big (bigger than 4GiB) files on a USB flash drive

[Walt Mankowski]

Hi,

I've run into this problem too. VFAT does in fact have a 4 GB file
size limit. Since I needed to use the drive on both Linux and Windows
I reformatted it as exfat. Ext4 should be fine if you only want to use
it on Linux.
