Okay my bad I didn't pay attention I thought it was a part1 part2 structureDont work(
First of all the archives are badly named. They all need to share the same name. Once you've downloaded them all, rename them. Instead of KiraModsALL-zip-Icawso2h.zip.001 and whatever comes next, the files should read KiraModsALL.zip.001 KiraModsALL.zip.002 KiraModsALL.zip.003 (...) and so on.
When you're done, open the first archive with winrar (it should be the only one with winrar's icon showing up) and extract everything, it will work as if every archive was one. I've tested it and it worked.
