but there still have platform folder in c > program files > MetaTrader 4, 5 > expert and indicator folder [ MT5 ]  and no expert indicator folder in MT4

just to make sure if the platform folder in program files is useless ??

and every indicator , expert just need to store at roaming folder ?

They've been located in the roaming folder for a very long time. But the "platform" folder isn't "useless", there are still some important things located in there.
