I am new to ArcGIS and have come across a problem. I am using Climond Data (.asc file) but need to reduce the area to only include Australia. When I clipped the layer using the Toolbox --> Raster --> Clip, the new file that was created changed to a .ovr/.adf file/s. I am wondering how to either change the newly created files back to an .asc file (only keeping Australia) or how to clip the file and not have it change in the first place.
I am sure this is easy once you know how to do it but I just can't seem to figure it out.
