I don't know if I understand what you've described - a filename - a folderpath?  
Hmm ...

Having such a foldertree:

```
ABC
--CD1
----01.Track.mp3 ==> DISCNUMBER: 1/2
----02.Track.mp3 ==> DISCNUMBER: 1/2
--CD2
----01.Track.mp3 ==> DISCNUMBER: 2/2
----02.Track.mp3 ==> DISCNUMBER: 2/2
DEF
--01.Track.mp3 ==> DISCNUMBER: 1/1
--02.Track.mp3 ==> DISCNUMBER: 1/1

```

With the following actionsgroup you can create proper DISCNUMBER values.

Begin Actionsgroup **Set DISCNUMBER n.1.2**  
Action #1  
_Actiontype 5:_ **Format tag field**  
_Field:_ **DISCNUMBER**  
_Formatstring:_ **$if($eql($regexp(%\_directory%,^._÷_(CD)÷\*\d+._$,$1,0),CD),$regexp(%\_directory%,^.÷CD÷_0\*(\d+).\*$,$1,0)/2,1/1)**  
Note: Replace one special character ÷ with one space character.  
End Actionsgroup **Set DISCNUMBER n.1.2** (1 Action)

Example for3 CD's:

Begin Actionsgroup **Set DISCNUMBER n.3**  
Action #1  
_Actiontype 5:_ **Format tag field**  
_Field:_ **DISCNUMBER**  
_Formatstring:_ **$regexp(%\_directory%,^._÷_CD÷_0_(\d+).\*$,$1)/3**  
Note: Replace one special character ÷ with one space character.  
End Actionsgroup **Set DISCNUMBER n.3** (1 Action)

That's it precisely.

Thanks, but I was hoping for something that would automatically set the discqty e.g. for albums having (so far) 1,2,3,4 and 10 discs.

Clarification:

I have multi-CD albums filed myalbum\1\track1.wma, myalbum\2\track1.wma etc. How can I automatically set DISCNUMBER to /? Thanks.
