Conversion of etrg files to mp4 file format

It is likely that your .etrg file is already an MP4 file (or some other multimedia format) and you just have known file extensions hidden in your system, so not etrg to mp4 conversion is actually required. Just enable file extensions in your system and you should see the actual file ending.
