I use
http://www.freeservers.com to host my file dump.. you can choose a sub-domain name and their name and have a free ad supported file server where you can put Word, Excel, PDF, jpg, etc file by using a web based File Manager or FTP supported file uploads.
They'll ask you to choose a domain name, but scroll down to the bottom and select a sub domain like 8m.com or s5.com so you dont have to register a domain.
