I've tried to make a new column in which I could see the URL from file, but it's not working. I've tried some values like %URL% and %WWW%, but it's not working. What value should I use? I need to delete URLs from around 1300+ files, so it's kinda hard to do manualy. If there is a way to do it in Mp3tag, I would like to know.
Thanks

Hello!
Select one file containing an URL and press [ALT+T]. In the new window, you should see the field names, an equal sign and the field values. If the URL is stored inside the _WWWARTIST_ field for example, you would have to use _WWWARTIST_ when creating the custom column.
I hope that helps.
Regards,
Sebastian

One more thing - if you want to _remove_ fields from an audio file, you can select all files you want to edit, press [ALT+T], select the fields you want to be deleted, click on the red X and finally hit OK.

Thanks. Field name is %Wwwuser%. Is there any way to delete all field values from my files? I've downloaded my files from pay site and it generated tags with URLs in it.

I've wondered today why I hadn't used Alt+T before. The answer is that this feature became available only in v2.17 and I had v2.16. I've upgraded only in 10 minutes before asking questions here. And when you were typing an answer I found Alt+T combination in menu. And there I found the %Wwwuser% field.
It's a great program. I like it much and it's so easy to use that I'm terribly sorry to ask such a stupid question before trying to read more about new features. I was just to anxious to try used-defined columns : )
