You want to change the filename of every track, right?

You can't use the `"` sign in a windows filename, because this [is a invalid character](https://en.wikipedia.org/wiki/Filename#In_Windows). Like the `?` or `*` and some others. But you could replace it with similar looking characters like two `'`.

Could you please show us with a [screenshot](https://community.mp3tag.de/t/hints-for-asking-support-requests/56190#use-screenshots-to-exemplify-the-issue-2) where you see this information `CD, 7", Single, Maxi` in your used Tag Source result window for your album?
