> [@nwr1cxo](#): > > ... I see a lot of different formats for the track numbers and was wondering what is the correct / best format to use. ... Are there pro's and con's of using one over the other. ... The number format for the tag-field TRACK depends on the media file type (mp3, wma, mp4, ...) ... this means ... - the tag-field TRACK can be of datatype numerical (1, 2, 3, ...) - the tag-field TRACK can be of datatype string ... e. g. with leading zero (01, 02, 03, ... or ... 001, 002, 003, ...). For displaying the number value from the tag-field TRACK in a readable format, ... you may code such a formatstring like this one ... **$num(%TRACK%,2)** ... and together with the number value from the tag-field TOTALTRACKS, .... you may code such a formatstring like this one ... **$num(%TRACK%,2)'/'$num(%TOTALTRACKS%,2)** Keep in mind, that the technical datatype of a stored value can be different from the human readable presentation of the stored value.
