Sending large files can be done in several ways. Here are the two I am most comfortable with:
Method 1: Discord - If you have Nitro.
That's it - that's the content. You send the file via Discord.
Method 2: Litterbox.
Litterbox is a free service that allows you to upload files which automatically get deleted after a certain time period. Chose a reasonable expiration time (like 3 days), upload your file - and send me the link!
