As a privacy-conscious user, I always worry about the 'Save As' dialog, and especially the 'Upload' dialog. I know the Upload dialog enables websites to perform certain operations of files without even uploading them. Can anyone please clarify: How much access to my computer do these dialogs give websites? Can they see all the files in the selected folder, even files I haven't selected? Can they look inside sub-folders, or even the parent folders? Can they tell the full path of the directory? Do they know my PC name? I want to be sure.
