How can I delete the coordinate system from a raster file like .adf which is multiple files?
I found a file with tha name "prj.adf" so if I delete this file is it enough?
In shapefiles usually Ι delete the .prj file and thene I define the projection again, if necessary.

This data is in Esri Grid format and I would not advise deleting its prj.adf file because that may be referenced elsewhere in its binary structure.
As @Craig said you should instead use the help instructions for Defining or modifying a raster's coordinate system.
