HTML5 where can I find .sav file?

I used save to slot node in my blueprint to save my player score data, but when I was playing my HTML5 game, I didn’t find .sav file in my project file.
The purpose I want to find the .sav file is that I want to update my player score data to the server so that everyone plays my HTML5 game can see each score on the website.

Hi @Prahlad Makwana
Thanks for helping me.
I can find the .sav file in Windows Package Version, however, after I packaging HTML5 version, I can’t find the .sav file.
It really makes me crazy.
I have searched almost all the information about this problem, but no one could figure it out.
Any solution is appreciated. Thanks anyway.
