Because my Treo 650's MP3 player (pTunes) does not display the Comment field, I need to append the Title of some of my MP3's (in a set of directories) so that the new Title field contains
Comment - Title
How do I do this?
Thanks.

Please read the [FAQs](https://community.mp3tag.de/t/967/1). 🙂
**%comment% - %title%** is the formatstring then.

Thank you.
It wasn't clear to me if the action was to be a "Format Value" or "Replace" or "Replace with Regular Expression".
Using Format Value seems to have worked.

PS: What an awesome, powerful program this is!!

I have a follow-up question:
How do I reverse this action?
Say, sometime in the future, I want to get back to the original content of the Title field. How do I do that when the current content of the Title field is actually
%comment% - %title%
How do I remove the "%comment% - " part of the Title field content?
Thanks.

Create the following action:
Action #1:
_Action type:_ **Replace with regular expressions**
_Field:_ **TITLE**
_Regular expression:_ **^.\* -**
_Replace matches with:_
[] case-sensitive comparison
Edit: In the regular expression, there is also a blank after the dash: " **^.\* -**" (without quotation marks).

Hi,
How do I delete the string before the first (going from left to right) appearance of " - " only?
Sometimes my Title has a " - " (no "'s in the title) in it from before. Adding the Comment field to it results in multiple instances of " - " in the Title. The above expression removes everything before the last " - ", not the first " - ".
Thanks.

Does this work:
Action #1:
_Action type:_ **Replace with regular expressions**
_Field:_ **TITLE**
_Regular expression:_ **^(._) - (._)**
_Replace matches with:_ **$2**
[] case-sensitive comparison

Instead of "^.\* - " use "^.\*? - "

Sebastian: the "^(._) - (._)" -\> "$2" did not work.
Dano: "^.\*? - " -\> "" worked !!
Thanks to all for the help.
