I'm not sure if this is the appropriate area, but since it has to do with S2PCI I might as well. The program works fine, but I have a question.

I have a bunch of files with letters and numbers, but it doesn't tell me if its a recolor, a mesh, nothing. I click it for a preview but nothing shows up. How do I know if it's a file I need? Are there any programs available that can tell me what they are?

It would be so great if someone could please help me Thanks, Luna.

Delphy's Download Organiser is much much better at identifying types than Clean Installer - search for his username here and you'll find it. Still won't give you a preview - it doesn't have a preview function but if CI won't then it's an item that has no texture - probably a mesh, hack, etc., but it will at least tell you what type it is.
