for example i see some records (no pun intended) are missing Codec data, and nowi find i have many null Year values

[image] dec: are missing Codec data These files are usually corrupt or have an unsupported format. For more information about filters, see (really!) [image] Filter and Search – Mp3tag Documentation Documentation on Filter and Search and keywords to form complex filter expressions…

Any of the file technical information (i.e. fields that start with an underscore character like %_bitrate%) cannot be written, but are pulled from the file info itself. If these are missing, they were not written by the original software. Metadata values that can be written or changed like Year can…

[image] dec: sourceforge and Github, binaries etc The alternative is to delete the files that show no codec.

so they cannot be matched and imported from some source?
