ECM File - opening and understanding

Did your computer fail to open an ECM file? We explain what they are used for and recommend software that we know can open or otherwise handle your .ECM files.

What is an ECM file?

ECM is an acronym for Error Code Modeler. Files that contain the .ecm file extension normally store modified disk image copies. User's commonly use this file format to create back-up copies of their computer hard drive's contents.

Unlike many disk image formats, the ECM file format allows for better file compression than the typical archive file format. This saves on disk and drive space when copying a hard drive into the ECM file format.

The Cmpro software application has also been known to use the .ecm file suffix. These ECM files contain example files that are used by the Cmpro software.
