Direct-read formats are used directly from the Catalog tree as read-only datasets. When you add them to ArcMap, ArcScene, or ArcGlobe, all standard map functions are enabled, including attribute tables and labeling functions.
Usage
Using a direct-read feature class inArcMap is similar to working with other geodatabase feature classes. You can snap to geometry, substitute symbology, query attributes, and use it with all geoprocessing tools that accept feature classes or layers as input.
To edit the data, you must convert it to a geodatabase format using the Quick Import tool or a spatial ETL tool.
