Here are how many applications you can include in the new folders of iOS 7

  In iOS 7 Apple Lossless Audio CODEC (ALAC), implemented the possibility to page the application folders, this basically giving us the option to view more applications in the Springboard of our iDevices. Practically, each folder can display 15 pages of 9 applications per page, so in total we have 135 applications displayed in just one of the folders in iOS 7. Considering that in Springboard we can display 20 folders in the 11 pages of Springboard, I leave it to you to do the calculations to see how many thousands of applications you can display in terminals.
