The MRF file extension is related to MultiEx Commander, a program developed by WATTO Studios for extracting data from hundreds of different game resource files. An MRF file contains program data used by the software.
MultiEx Commander is designed for Microsoft Windows. MRF files are mainly useful on a Windows system where the corresponding program is installed.
Open an MRF file with MultiEx Commander on Microsoft Windows. Because the file contains program data, it is not intended for meaningful display in a text editor or image viewer.
MRF files contain MultiEx Commander program data and do not normally have a useful conversion target.
