Not a day goes by that I don’t send or receive a humungous file so knowing a few different ways to get around your ISP’s file size limit is important.
I have only used one of the following services so my experience is limited, but if all of them are anything like YouSendIt I am sure you will be pleased with the results.
YouSendIt allows you to send up to a 100MB file without creating an account. Upon uploading a file to YouSendIt, an email is sent to the recipient, where they are given a link to download the file. The download is available for 7 days and includes advertising on the page.
Perhaps the simplest of the file transfer services, zUpload offers you up to 500MB to share a single file. A unique URL is generated for each file and is available for 30 days. Unlike the other services, there are no user accounts or premium features at the moment. It appears zUpload is entirely advertiser supported.
Based in the UK, MailBigFile functions almost exactly the same as YouSendIt. Without registering, you can send up to a 100MB file.
