I downloaded knoppix, mandrake and knoppix std for bittorrent. All 5 files indicated they were iso's, but then I uncompressed the filed they were folders. I tried to burn the contents of the folders but that didnt work, all there was was an autorun. I had seen a couple of images in the folders i downloaded but they seem to be only boot floppy images. Where is the iso i was supposed to get?
