how not to open all files in a folder in Notepad++

Question

Trying to filter file types in Notepad++ Open file dialog box opens all files of that type in that folder

I tried to go through the Options but given they are so many, can't seem to figure out whether one can get Notepad++ to just show the files of that type instead of opening them all

I don't have any code for this

Expected results: show all files of a file type Actual result: all files are opened.
