You can configure FileBot to use a different file chooser implementation if the standard Windows file chooser does not work for you for one reason or another:
Properties: Select all
net.filebot.UserFiles.fileChooser=Swing
See Advanced Settings for details.

Alternatively, you can use drag-n-drop to drag files from Windows Explorer into FileBot.

Alternatively, you can use CTRL+C to copy files in Windows Explorer and CTRL+V to paste the file paths into FileBot.
