Deleting movie files

Hi. I have installed ATV Flash. I transferred some AVI movies from my computer to my ATV using FTP. The movies end up in the Jaman folder on the ATV. How do I delete a movie file when I no longer want to keep it on my ATV? Thanks.

You can delete files using the same FTP client you used to initially transfer the file over.

Could you paste in a step by step guide to deleting files from the FTP client ? as i have had no luck on this.
