Open Pudd, choose to copy file puppy-1.0.6-mozilla.iso to a fat32 partition of 500mB and 1000mB. Pudd says it will grow the filesystem (~58mB) to fill the partition but I get an error saying:
Sorry, the destination partition is too small. The source
/root/my-documents/puppy-1.0.6-mozilla.iso is Kbytes but the destination
/dev/hda5 is 488976 Kbytes. Try again...
Perhaps Pudd is comparing source X bytes to destination Y kilobytes instead of kB to kB. Note it doesn't display a size for the iso.
