Hi, Happy New Year to everyone! I have a problem to set the field 'File nane' in the lateral tag panel. Since it was not present as a field among the items, I added it myself. But the entry does not appear in the field ... This is what i did: Right click on the tag panel, appears mp3tag option window, I select item 'tag panel' from the list on the left. In the center there is the list of fields visible in the tag panel. I click on the first button on the top right 'Add/Edit field'. I fill in all the items and in the first, in 'Field' I select 'ORIGFILENAME' from the drop-down menu. But obviously it is wrong because once everything has been saved, it does not appear in the Tag Panel field. I also tried to change the item from the drop down menu but nothing ever appears. Can you help me? Thanks a lot ! ![Tag edit File](https://community.mp3tag.de/uploads/default/original/2X/3/3abd6731eda05e4ac79dd79e535483ec3fdb15c1.jpeg) ---

To address the filename, use the property name \_FILENAME. The tag panel field definitions do not accept any field (or property) name that starts with an underscore - these properties are usually read-only and in most cases not handled by MP3tag. ---

Thanks for the reply. I tried to change but nothing happened. Could you explain me better? What should I write to direct it right on the filename? ---

You cannot edit the filename in the tag panel. You cannot add \_FILENAME to any item in the tag panel. This is not only valid for \_FILENAME but any property that starts with an underscore `_`, e.g. \_LENGTH, \_PATH, \_DIRECTORY, \_TAG ---

Ah ok, thanks. But, then, why do I see the Directory field? ![Tag edit File2](https://community.mp3tag.de/uploads/default/original/2X/0/0bc5c9f0a64d62c90fb9445f8d0a3f6c5200f290.jpeg) ---

The directory field is one that has been in the tag panel for a long time and you will see that it does not behave the way the other fields do: It has its own history of entries. It shows data even though no file is selected. Enter a new path in the field and that folder will be read and become the working directory. For all other properties with an underscore: don't ask "why", accept it as the way it is: they cannot be added to the tag panel as fields. ---

Too bad, it would have been comfortable. But anyway if that's the case ... we accept it. Thanks. ---
