Hi everyone ![:music:](https://community.mp3tag.de/uploads/default/original/1X/2ba05d1ade5eb0d15fc173be6f717dbe63890a70.gif ":music:")

I was wondering if you could help me with some code - I want to make every first letter a capital like this:

Elton John - Candle In The Wind

BUT - I want MP3Tag to do it so that if it sees OMD, DJ or MC, it leaves them be, or makes them caps if they're not.

Example: MC Solaar - Caroline or DJ Dinamique - Le Mix 2006.

Can anyone give me any ideas on this.

Thank you in advance and well done on a superb program!

You can add replace rules via Converter \> Actions... and apply these after renaiming the files.

Best regards,
