The conversion of the file M4R to CAF will allow you to edit a file using other software than before. The conversion M4R to CAF is particularly helpful in cases where you want to give certain features to the data in the M4R file, and all the programs that support the M4R format do not have the possibility to introduce the desired changes.
Just download one of the programs from the list and install it on your computer. After starting the program, select M4R file that you want to convert. Then select the target format (in this case CAF) and follow the instructions. Save the converted CAF file in the selected location. From this moment you can open the CAF file with all the programs that you will find here.
