The Icon Layout setting determines whether files in the file pane are listed in rows (horizontally) or columns (vertically). The default is row order. For example, if files are sorted alphabetically by Name in rows, they are listed in from left to right, with the first files on the top row, then the second row, and so on. If files are sorted alphabetically by Name in columns, they are listed from top to bottom, with the first files in the left column, then the second column, etc. Figure 2-38 shows files sorted by Name in rows, and Figure 2-39 shows the same files sorted in columns.
