The .adf files are components of a coverage, navigate the directory above the .adf files with the Catalog window in ArcGIS for Desktop to see the data.

Please check your data are intact, it should be in this structure:

this file is probably in esri grid format. Be sure have both the dataset and info folders. Catalog will only recognize data that is in the proper structure to be read; to see what's actually in the folder you need to use Windows Explorer.
