In the Asset browser, all items are arranged hierarchically within folders that you can expand or collapse.
To expand a folder, click the plus sign (+) next to the folder name. To collapse a folder, click the minus sign (-) next to the folder name.
The Asset browser lets you display the contents of folders in various layouts. For example, you can split the window horizontally or vertically to display contents in a separate pane.
In the second pane, you can display assets and other files with additional details as thumbnails or in a list. You can also use custom icons for your own files.
