Eugene's observations

To send a small file around, an e-mail attachment is the obvious choice, but many e-mail hosts refuse to handle much over a couple of megabytes.

The next possibility would be to upload the file to a publicly shared file server. Photobucket (http://photobucket.com/) is a good example but there are still limits on the amount of bandwidth and/or storage space permitted.

So for really huge files, after compressing to the max in ZIP or RAR formats, the easiest way is to set up an FTP (File Transfer Protocol) server and client. For enhanced compatibility and functions, eschew that available in the higher versions of Windows and go for something like Cerberus' FTP server at http://www.cerberusftp.com/

It is not hard or too time consuming to install, set up a user and add firewall exceptions on port 21. To maintain long term security, this can be closed at the end of the file transfer. At the other end a free FTP client (I use FileZilla from http://filezilla-project.org/) will enable a connection to be made and the most efficient transfer possible.

Depending on DSL upload connection speeds, 4MB a minute is a rough speed to expect.
