I created a Google Takeout file for my emails in my old gmail account which I am trying to import into my new gmail account, however the system does not allow me to split the files into smaller sections say 2-4GB which is what Thunderbird supports. I tried to submit for a 2-4GB split for the Google Takeout files and no luck...it always comes out in 2 files, one is a few MBs and the second file is over 40GB.

As I am trying to use ImportExport NG tool in the Local folders Mbox import, I get an error of Mbox All mail Including Spam and Trash-002.mbox larger than 4GB, skipping.

I've tried to find some online MBOX splitting tools, however no success as the file is too big and causing issues.

Any help with be much appreciated.
