Hello,  
I'm using this great program for more than 6 years.  
I need to check if the field isrc has some data for almost 20000 files.  
I could load the files with group of hundred but it'll take sometime to edit them all !!  
Would it be possible with some command line instruction ?  
If not, any help to speed up the process is appreciate.

Thank you in advance  
MM

See the documentation about command line parameters:

> **[Command Line Interface – Mp3tag Documentation](https://docs.mp3tag.de/command-line/)**
>
> Overview on command-line parameters to be used with Mp3tag. Mp3tag is the universal Tag Editor.

I don't really see how that is going to help.  
It is no problem to load

with  
%isrc% PRESENT.  
(BTW: if ISRC has no data, then the field does not exist).
