I ripped a CD to FLAC. When I opened the directory with Windows 11 File Explorer, I could see an album name, track #, and title. After I updated 1 of the files with MP3TAG, all that information disappeared and the properties sub-function could no longer update the details.
What fields did you update? Did that include large album artwork by chance?
see e.g. this thread about the problems that the windows explorer has with FLAC files:
I updated cover, title, composer, artist, etc.
And yes, the cover file is a large file.
I copied the large PNG file to a 3 MB JPG file and replaced the cover. Windows is still not happy. I then took another copy of the same FLAC file that never had the large cover art added and added the 3 MB JPG cover. Windows is happy with that copy.
It seems that MP3TAG should refuse to add the huge cover file and suggest instead a safe maximum size.
The "safe size" depends very much on the player - and the windows implementation of dealing with flac files is obviously flawed as it does not follow the flac standard.
As other programs cope without difficulties with standard compliant pictures, I doubt that MP3tag by default should hinder users to add covers well within the boundaries of the standard but outside the parameters that windows accepts.
Now that you know where the limitations come from, you can adapt your workflow and add only covers that the windows explorer can deal with.
There is an action that reduces the picture size.
You may need to have mp3tag compress the padding space left behind after changing the cover image size.
The "safe" size will depend on your own environment and player software. It isn't up to mp3tag to manage that. If it automatically reduced cover art file sizes, other users may be very unhappy with that. It is best left to the user to manage according to their needs. No different than any other tag limitiations.
Thank you so much.
I found the Optimize FLAC utility option and now everything is working.
