I thought that I might wanna try moving the folder into storage and creating a Shortcut in my Main Memory to save more space
But if possible, does the 'My Device\Windows\Messaging' contain important files?

Yes\No

Which files do they contain?
I'm guessing that it's emails and sms's right?
So if I were to delete them, would it affect my mails from my inbox once I Send/Receive?

its part of the system whicm may harm
I recommend you to try memaid trial, you can move the message files to memory card
