How to improve my File explorer dialog? [on hold]

This is the first time I am posting here, so sorry if I am making any mistakes.

I need to create file explorer dialog with specific functionality. I have done so but it just doesn't feel right. So I was hoping to get some input from you.

The dialog must have:

  • A list that will display existing files
  • An edit field to type the name of a file you would like to open or save as
  • A button for saving
  • A button for opening
  • A button to cancel/close the dialog
  • A button to open open a the folder where you save the files

This is what I came up with:

How can I improve it?
