automatic craziness


i connected to an ftp server on my intranet, and i don't know what happened, maybe it was because i clicked index, and maybe it is just the ftp client i am useing (fetch) but for some reason, the mac is trying to download everything in the home directory of the ftp server (which is a pc). i don't know why, and i don't know where the files are going, but i can see my hdd space shrinking away. i was trying to upload some stuff to the pc. please help.
Simply close the Fetch window or force-quit the application? If you haven't changed anything, it's downloading stuff to your desktop.
