Best and easy way to transfer large files (under 1Gb) over the internet to another computer?

Check out DivShare. I use it for this purpose all the time. Free, easy, and reliable.

yousendit.com used to work for me. I haven’t used it in awhile.

Before sending, zipping or archiving large files is a good idea to reduce the size. Most people have an unzipping program (WinZip, WinRar, Stuffit) already on their computer.

Divshare looks neat. I’ve always used Megaupload, but they limit you to something like 3x downloads from their site a day.

Use Bittorrent and yourself as the tracker and give the .torrent file to someone else to download. No third party required. Check out this link if you want to know how to easily do that.

Torrents is probably the most stable solution if you want to send a lot, but you can try PipeBytes for direct transfers.

You can also try ShareToad

Works not bad but simple.

You can use AIM. All you both need is a screen name and an internet connection.

I use an app called rake http://rake.slrsoft.com/ you can sign up for a free account and send 200mb files for nothing the best thing is it automatically encrypts your files so only your recipient can open them

I could not recommend Windows Live Sync enough. It is a fantastic product and works very well with PCs and Macs.
