First I would like to apologize for my English and then I will explain what the application does,
it allows you to select a video in a folder to initialize it in a player and by repeating this process we can therefore create a playlist,
the problem is that each time I close the application, the initialized videos disappear and I have to start the process all over again.

Thanks for taking the time to read me
