Hello, After several hours of fruitless research, I come to seek help here ! I have many files for which the ''Length'' column is empty. My goal is therefore to fill this column (or another) with the duration of each track (in miliseconds, it will be perfect). I create a new Column New: value: …

Please note that LENGTH is a field that has no significance in respect to the length of a track as determined by the creating program. The property for the length can be displayed with the variable_LENGTH. If you create a column with [image] fasu: value: empty Field: empty Sort by: empty t…
