Help can not install too many items

[lucaslucas50]

Hello, I have no META-INF folder, and I've got a dinosaur mod mod installed, so I try to add too many items and not sure of the error because the folder does not have too many items,

The folder does not have it?

Well, start fresh.

Force update your Minecraft.
Go into your .minecraft/bin/ folder, and open up your minecraft.jar with Winrar (or any other program like it). Make sure you have the mod you'd like to add downloaded in another folder. Now, delete the META-INF file in your minecraft.jar, and copy and paste all the files from the mod that you'd like to add into the minecraft.jar.

Load up Minecraft, and it should work. Make sure the mod is updated to your client version, and make sure you have all requirements. Some require having modloader, and some other mods.
