GMail Drive
An article on Tech Republic alerted me to this downloadable app which allows you to use the space available with your Gmail account for file storage. It's downloadable from SOFTPEDIA. After installation, GMail Drive will show up in My Computer like any other storage media. Uploaded files will show up in the list of emails in gmail with a subject line of GMAILFS: with the name of the file, so they will be accessible even if you are not on your home computer.
