Remarks

The Browse dialog box provides access to items that can be used in ArcGIS Pro, in the same manner as the Project pane. For example, a shapefile stored on a local disk is presented as a single item.

Some items may be available in the Browse dialog that are not available in the Project pane. Typically, these are items supported as inputs to or outputs from a geoprocessing tool, or items that can only be imported to a project.
