How can i insert videos in my k310i

Hi, not exactly an expert but just a suggestion is to see if you can move the files to an unexpected place but it is hard with sony ericssons because in the multimedia section is shows all files, memory card files and phone memory files so even if yu move em itll show it on all files. otherwise jus rename it to something dat starts wid a letter in the middle of the alphabet so it wont be da first ones or sumfing. sorry if that doesnt work.
