Any way to transfer file >4GB from PC to android tablet?
As Señor CMasMas has mentioned you need to format the SD card as ext4 and you will need root to be able to mount it on the android. You can access the ext4 partition on Windows with &quot;Linux File Systems for Windows by Paragon Software&quot; This program lets you mount the partition in windows and use it as a regular drive.
Here is how this can be done.

Format your SD card as ext4. You can partition it into 2 partitions and only format the 2nd one as ext4. This way you can still use the first partition normally on your device. I used Mini Tool Partition Wizard.
On your Android device, you need to mount the partition. I use Termux (terminal) to do this. You need root to be able to mount it.

Make a folder in your termux home folder where you will mount the partition. (eg. mkdir ext4).
Mount the partition to this folder. You need to find the device name. I have found in all my devices that it was /dev/block/mmcblk1p2 for my 2nd partition. (eg. mount /dev/block/mmcblk1p2 /data/data/com.termux/files/home/ext4-fs).



Once its mounted you can access it with Total Commander (and probably other file explorers as well) on the Android.
I have done this and am able to copy large files onto it.
