Hi,
I created a Form by mistake in Studio.
(red frame of attached image)

I want to delete, but I do not know how to erase.
where is it?

A very easy way to delete an application file from Studio is the following: 

1) Navigate to File > Settings (this will open "Application Settings" tab)

2) Scroll down to the application files section, select the application file to delete and choose the delete action
