[Asus Transformer TF700] mrjayviper:
I run terminal emulator on my tablet and run the mount command. (please see the line I underlined)

from what I understand, my microsd (which was formatted using gparted as ext4) is being mounted as an ext4 partition.

My problem is that when I tried to copy a bluray movie (around 6GB in size) I ripped, Windows8 says "the file is larger than the device" limit. I checked (settings => storage) and there's about 11GB of free space still available on my microSD.

so is there a way to fix this? thanks
