Isn’t it awful when you have to share a file too big for email and don’t know how? You’d think by 2016 we’d have that figured out. Actually we do, many times over. Just pick a standard that works for you!
If you don’t want to read many pages on file transfer standards (Samba? What’s that?) you can try this little snippet:
python -m SimpleHTTPServer $PORT
This will create an http server sharing the current directory. HTTP, luckily, is one of those things that tend to work everywhere, always.
