Is there a software which allows me to add a text note to a media file, such as MP4, AVI, etc.

Reason: some of the media files I have are 'events', such as a concert, a wedding party, etc. I want to add a 'side' file to it to describe the event. For example for a concert, its date and place, and the playlist. For a wedding party, the date and place, name of the bride and groom, etc. So, instead of embedding all these info into the file-name of the event, I have more space for descriptions.

Youtube have a very useful feature to describe the uploaded file as 'comments'... I am looking a similar thing for 'comments' add-on but just in Windows.

Appreciate help from all you good people to find and recommend me one.
