Best Answer

The .ovr file contains the image pyramids, which allows you to quickly and efficiently view images at a variety of scales. You can read more about raster pyramids here. These files are not intended to be opened or edited directly. They are attached to image files such as .tif format images. A more common workflow would be to delete and/or create a .ovr file. In ArcGIS, you can build pyramids using the Build Pyramids (Data Management) or Build Pyramids And Statistics (Data Management) tools. You can read more on deleting pyramids here.
