Similar to the ISO file, ECM files are images of physical disks. ECM, which stands for Error Code Modeler, is often used as a way to report problems in a Windows operating system environment. Opening an ECM file can be difficult, as there is not a native program that can read the file. Converting the ECM file to the ISO format will make it much more accepted by many different programs.
