It's not a mistake from my perspective, you're actively trying to modify a file that's being referenced.
It's the same principle as two people trying to modify the same document at the same time.
Because when you make changes a running mp3 track doesn't give an error but it is modified.
Yes, -visually- it appears to be updated, but (if I'm not mistaken) the changes aren't saved to disk until the track is no longer playing. This is true when adding/editing lyrics to a playing song. The changes display immediately, but the file isn't updated until the track is no longer playing.
That's right. You are right!!!
I did some testing and actually the saving only happens when you switch to another track or close the application.
Probably this case was not considered with asx files.
I have a lot of asx in a lot of compilations and unfortunately I often get this error, because this is an error, the program tries the modication of a file but cannot and therefore gives an error.
I don't understand why the discussion was moved to questions.
It is not a question but an error displayed by the software and that could be corrected.
Then if few people use asx OK there it is, but still error remains.
