I've been working on a game. I am not going to be able to have it under the google play size limit. So i will need it to have an expansion file. I was wondering how (if I can) I would go about having the game check if the obb file is already installed and, if not attempt the download using BP

I figure I will include the opening movie, and then just a level that throws up a widget splash screen. The level BP would have it.

Simple branch with a check, if found it loads main menu. If not then attempts download.
But I cant find any nodes for this for sure (I found ONE but it requires me to put in a URL and everything I know is that google makes a temp URL for each download)

Thanks in advance.
