Yes. That splitting files was especially useful because emails used to have attachment size limits.

No no no no
It was primarily used to post to USENET.
Back in the day, every byte of data was precious and bandwidth was insanely limited, nobody would ever email an attachment for that.
Due to some of the technical details about how email works, that would end up just bloating the file size and it would be the literally most inefficient way possible to send large blobs of data.
