Unable to import large mbox file into Thunderbird (macbook air)

[rkapatel]

I have followed the steps provided to import mbox file (with sbd structures) but nothing is happening when I select this option using the import-export-tools-ng add-on

@rkapatel What is the directory structure you have? Have you tried to import a single mbox? What is the source of the tree you have? @cleidigh
