I have transferred the .ipa whatsapp installer to an app called Xdownloader on my iPhone 5s running iOS 8.1.2 (jailbroken).
The .ipa file is about 110 megabytes. My free space was 1.7 gigas. I then deleted and installed whatsapp several times where each time I would open Xdownloader, click on the .ipa file, and choose to open it using "AppCake" in which I would get the option to install popping up right away.
Then I noticed that the free space dropped to about 300 megabytes! I can only presume that AppCake unzips the .ipa file to some temp folder and installs from it but doesn't delete it after the installation process completes! I navigated (using iFile) to all folders I could think of but couldn't find a thing! I also tried to clean up using iCleaner Pro. still, didn't do it.
I tried to remove both Xdownloader & Appcake altogether and reinstall them but then again it woudn't solve the problem. Appreciate any help

Looks like you imported (copied) an ipa to AppCake several times and all the copies are still there in a folder AppCake uses for storing ipas. It is somewhere in mobile.
