What he said. I don't think you can put a ton of apps in a folder anyway, unless there's a tweak for that.

In iOS 7, infinite pages of apps in a folder. 9 per page

With tweaks such as FolderEnhancer, you can increase that number to 20 apps per page. I personally have it on a 4x4 setting like with iOS 6
 
I'm not sure of a tweaks that can do this but you could reset the home page icons so there in alphabetically order then edit the IconState.plist and put them all in a folder
