A few days ago, I needed to send a file to someone over the internet. Not a particularly huge file, but at 30 MB it was still larger than most email systems would support. And even if my own system allowed it, there was a pretty good chance that the recipient's would not. So I set about looking for a system that was easy to use, free, and would allow me to send someone a large file.
In the end I opened for MailBigFile. You can find them at www.mailbigfile.com and the system is simplicity itself to use. If you want to take advantage of their free starter account, click on the Free button on their page. You can now send up to 5 files to people, and each file can be up to 2,000 MB in size. At this sort of size, you're looking at something which is as large as Windows can hold in a single file, so it's unlikely you'll need any more capacity than that.
To get started, drag the file you want to send into the box, and add the recipient's email address. It's pretty much as simple as that. The recipient will receive an email which provides a download link so that he or she can retrieve the file. And if you're worried about privacy, just encrypt the file before you upload it to the system.
