1. Select the current project in the Locations pane.
2. Select one or more items in the Browser pane.
3. Choose Delete from the Right-click menu.
4. Do one of the following:

Click
Move to Trash (Mac) or
Move to Recycle Bin (Windows) to remove the item from project.

Click
Delete to remove the items from your system.

Click
Cancel to leave selected items unchanged.
