How to remove file logicaly?

http://askubuntu.com – I have a file on my computer which was called just one.flv , I deleted this file but the problem here is that the icon of the file still appeared and when I try to do any operation on it from terminal , this message appeared No Such file or directory. Now I can't do any operation on it. I can't copy or rename or cut or delete. I tried: rm -f 'just one.flv' to force delete. Any help? (HowTos)
