I want to build web page. In this web page there are text box and buttons. By clicking on button it show open dialog with selected file types for example only (mkv and mp4). Then the path of chosen  file written in text box. Then do same thing 4 more times but with different files type. Finally, there will be SAVE button that will take all paths then save dialog appear to save it as txt.
I still looking for tutorials about thing that related to this but there are no one exactly as what I want.
Interface will be like:
Textbox01-OpendialogButton01
Textbox02-OpendialogButton02
Textbox03-OpendialogButton03
Textbox04-OpendialogButton04
Textbox05=OpendialogButton05
RESETButton-SAVEDialog Button

If anyone can help that will be great.
Thanks
