Script/blueprint to place txt file on players computer?

Simply saying, I was wondering if anyone would direct me to a way on, when an event happens, a txt file will appear on the players desktop or Documents folder.

I haven’t found much online about it, so any help would be appreciated.

This kind of Functionality is probably not exposed to BP. Look for C++ on AH or try Ramas Victory plugin he usually has that kinda stuff in there.
