Are you trying to identify one particular tune, or are you trying to get a big collection of merely numbered files to give up their names?

The answer will depend on whether the file was named using the original creation software or not. If it was, if you open the file using a raw data inspection tool (that will depend on platform) you may find the text string somewhere in the data.

Alternatively, you can open the SMF in a DAW and usually, if the song was titled, that may appear (or it might not, once again, it depends on the file and the DAW/sequencer).

As to a batch inspector (let’s assume that you have a folder with dozens of unnamed files), that I don’t think I have come across this. If it’s just a few files, no problem - you can hand open them one by one and either identify by ear or use the above to try and read any embedded data. Hundreds of unknown files on the other hand might not be so easy!
