The file browser will scan and show files in Application.persistentDataPath, limited file types (.kml,.kmz,.job,.dxf and .obj) are supported.

By selecting any available item in the list and optionally typing string in the input field, clicking "Confirm" button will log the item's name and your input string in the console. Clicking "Cancel" button will log the cancel button pressed event in the console.

It also has a ArcGIS Service item by which clicking allows you to add private web server (Portal) or public web server (Service Directory).

Items that are not simple container(e.g. directory) also have a star icon next to the load button. By clicking the star, the corresponding data item can be added to the Favorite item list. In My Favorite item, you can load or remove your favorite items.
