Process from multiple folders in a Batch

Hi all,

let's have a look. I've got two directories : A and B.
In directory A : picture1_A.tga, picture2_A.tga etc...
In directory B : picture1_B.tga, picture2_B.tga etc...

I would like to write an action which do something with picture1_A.tga and
picture1_B.tga, and then run a Batch which do the same action between
picture2_A.tga and picture2_B.tga etc...

I've found nothing in Help to do something like that. Only batching on a
single directory, or multiple directories (with the hint of targets), but
not in multiple directories in the same action !

Please help me

 

If you are an experienced programmer, download the Photoshop
scripting plug-in from Adobe's web site. If not, you could try
writing an action that runs the Batch command twice. Sometimes
I can get Batch to work inside an action, sometimes not.
