What are ECM files and how to open them

Are you having problems opening an ECM file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.

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.
