I use MP3TAG almost exclusively for my audiobook collection. I currently export an RTF file with the following data to the book folder. As most of the books are split into multiple files I only extract from the first file however that makes the files size and length data irrelevant. Is there a way to add the totals of the .mp3 files within the folder to give an album/book size and length? I don't really know what I am doing but have figured out this much by trial and error.
$loop(%\_filename\_ext%)
Book Title: \b %title%\b0\par
Series: \b %album%\b0\par
Author: \b %artist%\b0\par
Narrator: \b %albumartist%\b0\par

Audio Publication: \b %origyear%\b0\par
Genre: \b %genre%\b0\par
Length: \b %\_length%\b0\par
Size: \b %\_total\_size%\b0\par
Bitrate: \b %\_bitrate% %\_vbr%\b0\par

$loopend()

My apologies. Maybe I should have posted this in the Export subforum but I can't work out how to move the post??

Thanks a heap for the link. I managed to work out how to get total size and total time to work within the context of my export RTF however I can't work out how to make it limit to one entry. I see the (%fieldname%,num) but can't figure out how to use it in this context and end up with multiple entries when (as all tags are identical between the files except track #) I don't require the duplicates. Here is what I have. Any suggestions would be appreciated.
$loop(%\_folderpath%,1)$puts(album\_time,%\_total\_time%)$loopend()
$loop(%\_folderpath%,1)$puts(album\_size,%\_total\_size%)$loopend()
$loop(%\_filename\_ext%,1)
Book Title: \b %title%\b0\par
Series: \b %album%\b0\par
Author: \b %artist%\b0\par
Narrator: \b %albumartist%\b0\par
Book Year: \b %year%\b0\par
Audio Year: \b %origyear%\b0\par
Genre: \b %genre%\b0\par
Book Length: \b $get(album\_time)\b0\par
Book Size: \b $get(album\_size)\b0\par

really necessary, if you want to go through the data only once?

I have no idea. I created this by experimentation and borrowing from other examples. I have no idea how it actually works. I tried to use some logic but that only takes you so far. Reading the help file is somewhat helpful however I am coming from the place of a complete amateur.

Then please try to leave them out.

I'm not really sure what you are telling me to leave out because the export doesn't work when I delete the extra loop commands. I copied them from the example you linked to and they work. Are you saying they are causing the duplication?
EDIT: OK I get what you meant and got it working. Thanks
