I would like the length (time) column to display as MM:SS.xxx, with three decimal places displayed. I have tried using %length% and functions like div(x,y), but can't seem to get the syntax correct. Any suggestions? ---

Which field would show you the fractions of a second? The only ones I found are %\_length% and %\_length\_seconds%. To get the length out of the last field: $div(%\_length\_seconds%,60):$mod(%\_length\_seconds%,60) ---

Thanks, ohrenkino. That helped a lot! Here's what is 'working' so far: $div($mod(%length%,6000000),60000):$div($mod(%length%,60000),1000).$mod(%length%,1000) The only problem is that a time of something like 4:03.291 displays as 4:3.291. Is there a simple way of forcing the zero in 03 seconds? ---

$div($mod(%length%,6000000),60000):$num($div($mod(%length%,60000),1000),2).$mod(%length%,1000) or e.g. $div($mod(%length%,6000000),60000):$num($div($mod(%length%,60000),1000),2).$num($mod(%length%,1000),3) ---

Very, very nice! Thanks a million! You may have noticed that I didn't account for track lengths of 1 hour or more. I doubt that I even have any, so I'm not too worried about it. Thanks again, and enjoy the rest of the weekend! ---

This is strange. I only tested this for mp3 files, and it was fine. For FLAC files (which is what I use the most), I get all files with a time of 0:00.000. ??? ---

Try %\_length% instead of %length% ---

Thanks for your reply. When using: $div($mod(%\_length%,6000000),60000):$num($div($mod(%\_length%,60000),1000),2).$num($mod(%\_length%,1000),3) I get 0:00.004 for a song that should be 4:03.291. This result is for both mp3 and FLAC. Also, if I use %\_length\_seconds% only, I get the number of seconds rounded to the nearest second. So %\_length\_seconds% won't give me fractions (decimals) of a second. ---

See e.g. the help on variables with technical information: > **[Format Strings and Placeholders – Mp3tag Documentation](https://docs.mp3tag.de/format/)** > > Documentation on format strings and placeholders to describe the structure of file names and imported data. Mp3tag is the universal Tag Editor. I think that %length% was a user-defined field, inserted by the converter. An apparently the converter for flac does not add this field. ---

Yes, I had already been looking at that page you linked to. I'm wondering if I could use the bit rate somehow. Take the file size (in kB) and divide it by the bit rate (in kB/s), to generate the time in seconds. I'll have to experiement some more. Thanks for your input. ---

I was wondering if there might be something I could add to Options --\> Tags --\> Mapping that would work for FLAC files to extract the length (time). Anyone know? ---
