Hi, If you deleted the files from the firefox downloads window then the files should be located in your downloads folder, you can find out where this is by selecting the tools menu and clicking of options, this will open a new window and your download's location will be shown in the genral tab. if you downloaded them from iTunes the should be in your iTunes folder, this is located in "My Documents\My Music\iTunes\iTunes Media\" However if you deleted them from your hard drive, this has nothing to do with firefox and there are two things you can do, look in your recycling bin and see if they are there and restore them, or download them again, as for where to got them i can't help Dan
