When a path is viewed, files will be displayed as they are and directories will be displayed with a system file separator appended (e.g. "/" for Unix systems). Single click on a file name will make the file selectable when the select button is pressed. Multiple selection is possible by dragging with mouse button 1 pressed. Double click on a directory name will go into that directory and display its files. When a file/directory is selected and the "End" button pressed, the full path for the selected files selected will be returned.
