Project Browser

In this view, you can access and manage the assets that belong to your project.

The left panel of the browser shows the folder structure of the project as a hierarchical list. When a folder is selected from the list by clicking, its contents will be shown in the panel to the right. You can click the small triangle to expand or collapse the folder, displaying any nested folders it contains. Hold down Alt while you click to expand or collapse any nested folders recursively.
