Thanks. I hope that you have filled the usual tags like artist and title. Then, to rename files, use the converter "Tag - Filename" (menu convert) and enter a mask e.g. like this: %track% - %artist% \_ %title% (this assumes that the tags for artist and title are not empty). If you want to get leading zeros for the track number then use a mask like this: $num(%track%,2) - %artist% \_ %title% Have a look at the preview function that gives you an impression of the converted filename. Also please not the arrow button on the right in that dialog that opens a list of available tags to be added to the mask. have fun. ---

Hi, also just want to add number before the track having used this code with the tag to tag converter: %TRACK% $num(%track%,2) %title% And the preview shows the correct coding but after pressing ok nothing has been changed. What is wrong there? ---

> [@Joeger](#): > > tag to tag converter: > > %TRACK% > > $num(%track%,2) %title% The function Convert\>Tag-Tag modifies the contents of a tag field or another property like \_FILENAME. You would have to choose the correct converter - I would choose Convert\>Tag-Filename is the best to rename files. If you insist on Convert\>Tag-Tag then you would have to use \_FILENAME as field without the %. The syntax %track% for field is invalid. ---

Thanks, but Convert Tag--Filename does not work, because I want to keep the filename and the tagname. But before the filename should be a prefix with the track number like: OLD: track1 track2 track3 and NEW renamed as 01 track1 02 track2 03 track3 Thus I need the tag-tag function. But even replacing track and title with \_filename in my code above does not bring the result. Could you give me the exact code for the first and the 2nd field for the tag-tag converter, please. Thanks. ---

If you insist on Convert\>Tag-Tag then still use as field: \_FILENAME Format string: $num(%track%,2) %\_filename% ---
