What are ECM files and how to open them

What is an ECM file?
An .ECM file is an Error Code Modeler Disk Image file.
ECM is an acronym for Error Code Modeler. Files that contain the .ecm file extension typically store modified disk image copies. Users commonly use this file format to create backup copies of their computer hard drive's contents.
Unlike many disk image formats, the ECM file format allows for better compression than the typical archive file format. This saves disk space when copying a hard drive into the ECM file format.
