FATFILE="/path/to/big_fat_file.zip"
SAVEPATH="path/to/save/split/files/part_" # notice the end is '/part_'

# 3221225472 byte = 3GiB // perfect for FAT32... (main reason to split files..)
SPLITSIZE="3221225472"

split -b $SPLITSIZE $FATFILE $SAVEPATH

2_join.command

#!/bin/bash

clear
echo -ne "\n\n"
echo "This action will take some time!"
echo -ne "\n\n"
