Recently I have had to send some files that are too large to e-mail. Most e-mail services seem to have a 5 MB (or less) attachment limit. I’ve been using YouSendIt.com and it has worked very well. You upload the file to this service and the person to whom the file is directed receives an e-mail from you including the link to download the file. The file is available for a few days and "a limited number of downloads." This service’s file size limit is 1 GB (or 200 times most e-mail service’s limit.) Best of all, it is totally free.
