Hi there,
I'm using Mp3tag for quite a while but just discovered that Actions are exactly what I need 😊 I'm running Mp3tag in Wine as there is no such good and usable tool natively on Linux. I created some Actions for my usual workflows and discovered a bug (I think).
I am using the "Format value" action for \_FILENAME and this format string: `"%artist%\%album%\$num(%track%,2) - %title%.%_extension%"`
> File
> "Z:\home\user\Music\ToDo\Artist with Questionmark\_\AlbumX\01 - Title.mp3"
> cannot be renamed to
> "Z:\home\user\Music\Artist with Questionmark\AlbumX\01 - Title.mp3"
>
> Path not found
The artist is "Artist with Questionmark?" which is of course not a valid path for Windows software. The "Tag -\> Filename" feature which I used to use did never have a problem with this, though (even under Wine). It just removes the invalid characters from the path. So my guess is that at this point the paths aren't sanitized correctly/completely.

You could try it with [$validate](https://docs.mp3tag.de/scripting/#string-functions).
Something like:
`$validate(%artist%\%album%\$num(%track%,2) - %title%.%_extension%,-)`
I'm not sure, if this works on Linux/Wine too. It should replace all the non valid characters like ? or \* with a -. Feel free to change the replacement character.
