The size restrictions on e-mail attachments depends on the Mailing Service., but generally most at 40MB.
Some (Business) will allow MUCH larger files to be shared... I think mine has a 5GB Limit Per E-Mail or w/e you / your business has setup.
Beyond this there is Google Drive, OneDrive and a few others.
Plus obviously Skype lets you share files (but that used to be a bit hit-and-miss... not sure if that's improved) and I've been using Discord almost exclusively for the past 5 - 6 years (however long Discord has existed), and on there you can setup Private "Servers" / "Room" for you and your friends; where you can Share Files, Memes, Videos, Voice Chat, Text Chat, Video Chat, Stream Games, etc.
Funnily enough., was suggesting it to my Brother the other month as a great way for his Kids to talk to me and our other Brother; his response was "Discord, isn't that the [adult content] sharing service?"... that threw me, as I've always used it for chatting with friends., be it other gamers or developers.
Apparently (to him anyway) the only time he'd seen Discord was people sharing Discord Links on Facebook that were full of various Adult content.
I think it speaks a lot to how we use the Internet, as I literally had no idea people were using Discord for that... just assumed it was mostly used by Gamers for shooting the breeze while playing Games (you know it's intended purpose :-p) but I mean doesn't surprise me... I mean a free service on the internet... of course it's going to be used to share adult content :-p
Heck, remember Moderating these forums 15+ years ago... you'd get people creating accounts just to spam the most obscene fetish images., so that was always fun spending an hr every few days deleting massive numbers of posts with things that I wish I could unsee.

Now in any case., there is unfortunately no "Print" Option in AppGameKit Studio.
It's a shame... as I think it would be useful to be able to convert to a Printable Document, like say a PDF to either Print or be able to snippet for Whitepapers / Tutorials.
For products you create., well they're stored in the Project Folder (I changed this to a separate Drive) and if you hit F4 it will built the Runtime (.exe) without also running an Instance of it (F5 is Build & Run for Testing).
Then you can just zip up the Project Directory and send it to your Friend.
Now as a note, strictly speaking the Runtime (.exe) is just the AppGameKit Player., which is built to include the Function Libraries you're using.
So really all you have to share is the Bytecode.byc (and any media you choose to add) and it'll "Update" the game.
