Android Question Is it normal that .html files in Objects\bin\extra\assets dissapear after compile/run? [Solved]

I've placed a disclaimer.html file in Objects\bin\extra\assets folder
After compiling/running my program to display disclaimer.html
using:
WebView1.LoadUrl("file:///android_asset/disclaimer.html")
I get an error message:

Web page not available
It was not possible to load the web page
file:///android_asset/disclaimer.html
because:

net::ERR_FILE_NOT_FOUND

After this trial, I checked the folder with windows file manager and it's empty with a message saying we are working on it
