Free file sharing sites are a dime a dozen out there, however every so often one catches my eye.  S4ve.as allows you to upload any tile of any size for free and get a link back to it that remains good for 24 hours.  So if you need to quickly send a big file to a friend, this offers itself up as a great solution.

Once you get the link, copy and past it anywhere and share it instantly via e-mail, web page, instant message, status update, tweet, etc. Links are automatically shortened using bit.ly.

The only catch that some people might not like is the link is only live for 24 hours, after that the files in question are removed.  However, if you need a quick way to share anything – S4ve.as is an option better than most.
