Jigsaw Download

Jigsaw Download, or jigdo, is an intelligent tool that can be used on the pieces of any chopped-up big file to create a special template file that makes reassembly of the file very easy for users who only have the pieces. What makes jigdo special is that there are no restrictions on what offsets or sizes the individual pieces have in the original big image. This makes the program very well suited for distributing CD or DVD images (or large zip or tar archives) because you can put the files of the CD on an FTP server--when jigdo is presented the files along with the template you generated, it is able to recreate the CD image.
