Save layers in file named LayerSet

You can use this primitive method for given circumstances:

sTT = stringIDToTypeID, jpg = new JPEGSaveOptions()
jpg.quality = 12, set = (aD = activeDocument).layers[0]
Folder(folder = '~/desktop/' + set.name).create()
for(i = 0; i < set.layers.length;){
     nme =  set.layers[i++].name
     ref = new ActionReference(), lst = new ActionList()
     ref.putName(sTT('layer'), nme), lst.putReference(ref);
     (dsc = new ActionDescriptor()).putList(sTT('null'), lst)
     dsc.putBoolean(sTT('toggleOptionsPalette'), true)
     executeAction(sTT('show'), dsc)
     aD.saveAs(File(folder + '/' + nme), jpg)
}
