Hello Everyone

I want to change the way alot of my mp3s are written, for example i have a file called -

(06) [DJ Snowman] System Of Survival.mp3

But i would like it to be written this way -

1. DJ Snowman - System Of Survival.mp3

Is there anyway to do this in mp3tag? any help much appreciated, thank you.

Use replace with regular expression action in the **\_FILENAME** and use :

Replace  
^((\d+))\s+[([^]]+)]\s+(.\*)

With  
$1. $2 - $3

* * *

**EDIT**  
To can also make sure you have leading zeros, do this :

Replace  
^(0\*(\d+))\s+[([^]]+)]\s+(.\*)

With _(0$1 will return 01,02 etc and 00$1 will return 001, 002 etc)_  
0$1. $2 - $3

No problem. You can always use the mask then to right them values to your tags by doing:

**Filename \> Tag**  
%track%. %artist% - %title%

Or if your tags are Okay to begin with (without having ot do that step I explained in my first reply) you can use:

**Tag \> Filename**  
[**$num(%track%,1)**.][%artist%][- %title%]

Above will return (Notice the number of leading zeros and the mask in **bold** ):  
**6**. DJ Snowman - System Of Survival.mp3

And:  
[**$num(%track%,2)**.][%artist%][- %title%]  
**06**. DJ Snowman - System Of Survival.mp3

* * *

I'll edit my first post to show you how to make sure you have 01, 02, 03 etc as opposed to 1, 2, 3 in the filename with that method.
