452 error

When trying to updload to my web page using SmartFTP, I make connection fine with my server but get the message 452 Insuffcient Storage Space. Would this be my allotted web space or a function of FTP ? The page was presently loaded on my site and when I made an update it refuses to upload.
Thanks

Your server is full, or the file that you are trying to upload is to big for the remaining space.
