Old .m4a zip file on PC and forgotten password

I've been doing a much needed clean up of rubbish I've saved over the years. I've found a file I created in 2011 with a password but no idea of PW I used. I'm reluctant to just delete the file until I know what it is. I'm not very techy but see the file compressed size is 5,700 KB ratio 2% CRC-32 0BBCD7A4. Is this a hopeless cause or is there a way I can open it? Many thanks for any suggestions.
