It's a very useful tool that performs exactly what it claims. Simply drag and drop the large MBOX files into it. With the trial version, I was able to split a few files. Then I purchased this Standard Package, which is sufficient for me at this time. There is no ad, no solicitation to subscribe, or to sign in.

One of my favourite tools. It does so much and is such a useful tool. Some of the applications I discovered can perform a lot on their own, but this software can handle complex tasks like splitting multiple MBOX files. It transforms this software into a saviour. One of the nicest features is the opportunity to choose the files needed.
