md5sum is a program to check to make sure that the ISO image file you downloaded is good. The file came with Linux Distribution (Mandrake, RH, SuSe Etc.) The md5sums file is tiny--it is only a two line ASCII text file that contains the name of the ISO files and the md5sums that were calculated on their machine (i.e., before being downloaded.)

calculate the md5sums of the ISO images that been downloaded.

md5sum -b *.iso
e258584f8ebcf1d5d16ad63a51eb9321 *Mandrake72-ext.iso
ffcd786f04c76d193379eed4670ecfde *Mandrake72-inst.iso

Check man md5sum for more information.
