which file?

[Glenn Ervin at Home]

I went to an FTP site to download the latest version of Fedora, and I
noticed disks 1 through 4 with one name:
FC2-i386-SRPMS-disc1.iso
and after that, there are 4 disks without the SRPMS in the name.
What is the difference?
Thanks.
The site is:
ftp://linux-speakup.org/pub/linux/speakup/disks/fedora/current
Thanks.
