Where does it place the file?

Binary package hint: transmission

Fresh install of Lucid. Went to Ubuntu to download the Beta 2 AMD64 desktop image. Transmission downloaded it successfully and is now seeding. However, the file is nowhere to be found! The default is $HOME/Downloads. My Downloads folder is completely empty. A search of my directory using 'find $HOME -name "ubuntu-10.04*iso"' yields nothing. So I am seeding a phantom file...
