Hi,
I have some mp3s that do not contain the catalog numbers in them. The folders in which they reside though do contain the catalog number. Does anyone know what action it would be to copy the cat numbers from the folder names into the %catalog #% field in the tag?
The folders are in the format: Artist\_-\_Release-(CATNUMBER)-Year
Many thanks in advance

_Actiontype 7:_ **Import tag fields (guess values)**
_Source format:_ **%_directory%_**
_Guessing pattern: **%dummy%** _**-\_%dummy%-(%catalog÷#%)-%dummy%**
Note: Replace one special character ÷ with one space character.

Thanks DetlevD works like a charm!
It looks like a can finally dump the Visual Basic program I've been trying to get to work to do the same thing!
I have one more request it thats ok?
Is it possible to to append something to the Album field based on what is found in the filename?
For example a folder is in this format: Artist\_-\_Release-(CATNUMBER)-Year-Source
If the Album field contains 'Release 001" and the Source in the folder name was 'SHOP' then could SHOP be appended to Release 001 to make Album: Release 001 SHOP ?
Many thanks again
