Looking to covert the "RELEASETIME" tag to filename to help organise podcasts in windows explorer.

The podcasts come with the release tag in the format DD/MM/YYY HH:MM e.g. 08/01/2016 06:00; would like to convert this tag to filename in the following format, YYYY-MM-DD.

Would someone be able to help kindly advise/share any ideas how to do so please?

Thank you 🙂

You can try  
$regexp(%releasetime%,'(\d\d)/(\d\d)/(\d\d\d\d).\*',$3-$2-$1)
