I have spent a long time (maybe too long) searching for free online file storage. I have put together a list of the top six best file storage sites. As always they are all completely free or at least have a reasonable free option. Here is a list of sites offering free service. No Trials or mandatory upgrades.  They are arranged from least to most storage, although usability seemed to go in the same order. Scroll down to the bottom or click HERE for a quick table comparison of all five.
