How to Send Large Files to Roadrunner Emails?

Emails were only used to convey messages back in the day, but things have changed over a period of time, new advanced messages have been added to the system and email services have become much better. I can’t remember when people could send attachments in emails for the first time, but it was certainly a long time ago. However, the files that people attached to emails were word documents, excel sheets, and PPTs. Now people send all kinds of things, from music files to videos and everything.
