This is part of Fedora. >From what I have read about rar, all the rar pieces are simply one archive that has been binary chopped up into n pieces. You can do that with any archive with the "split" command and then "cat" them back together. I have done that to chop up a large disk image to avoid the 2GB/file limit on FAT32 external backup drives: dd if=/dev/partition_to_be_read_from | gzip -c \ | split -b 2000m - /mnt/usb/image_name.img.gz. Then to combine them: cat /mnt/usb/image_name.img.gz.* \ | gzip -dc | dd of=/dev/partition_to_be_written_to /Mike
