Script to delete all empty folders & layers

Yes you should be able to use AM code as a layer has the following keys with Photoshop CS2
AD 01 = name : DescValueType.STRINGTYPE
AD 02 = color : DescValueType.ENUMERATEDTYPE
AD 03 = visible : DescValueType.BOOLEANTYPE
AD 04 = mode : DescValueType.ENUMERATEDTYPE
AD 05 = opacity : DescValueType.INTEGERTYPE
AD 06 = layerID : DescValueType.INTEGERTYPE
AD 07 = itemIndex : DescValueType.INTEGERTYPE
AD 08 = count : DescValueType.INTEGERTYPE
AD 09 = preserveTransparency : DescValueType.BOOLEANTYPE
AD 10 = layerFXVisible : DescValueType.BOOLEANTYPE
AD 11 = globalAngle : DescValueType.INTEGERTYPE
AD 12 = background : DescValueType.BOOLEANTYPE
AD 13 = layerSection : DescValueType.ENUMERATEDTYPE
AD 14 = layerLocking : DescValueType.OBJECTTYPE
AD 15 = group : DescValueType.BOOLEANTYPE
AD 16 = targetChannels : DescValueType.LISTTYPE
AD 17 = visibleChannels : DescValueType.LISTTYPE
AD 18 = channelRestrictions : DescValueType.LISTTYPE
AD 19 = fillOpacity : DescValueType.INTEGERTYPE
AD 20 = bounds : DescValueType.OBJECTTYPE

and here is a code example to get various details including bounds of all layers...
Code: Select allfunction getNamesPlusIDs(){
var ref = new ActionReference();
ref.putEnumerated( charIDToTypeID('Dcmn'), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') );
var count = executeActionGet(ref).getInteger(charIDToTypeID('NmbL')) +1;
var Names=[];
var doc = activeDocument;
if(doc.layers[doc.layers.length-1].isBackgroundLayer){
var i = 0; }else{ var i = 1; };
for(i;i<count;i++){
if(i == 0) continue;
ref = new ActionReference();
ref.putIndex( charIDToTypeID( 'Lyr ' ), i );
var desc = executeActionGet(ref);
var layerName = desc.getString(charIDToTypeID( 'Nm ' ));
var Id = desc.getInteger(stringIDToTypeID( 'layerID' ));
if(layerName.match(/^<\/Layer group/) ) continue;
var layerType = typeIDToStringID(desc.getEnumerationValue( stringIDToTypeID( 'layerSection' )));
var isLayerSet =( layerType == 'layerSectionContent') ? false:true;
var descBounds = desc.getObjectValue(stringIDToTypeID( "bounds" ));
var Left = descBounds.getUnitDoubleValue(stringIDToTypeID('left'));
var Top = descBounds.getUnitDoubleValue(stringIDToTypeID('top'));
var Right = descBounds.getUnitDoubleValue(stringIDToTypeID('right'));
var Bottom = descBounds.getUnitDoubleValue(stringIDToTypeID('bottom'));

Names.push([[Id],[layerName],[isLayerSet],[Left],[Top],[Right],[Bottom]]);
};
return Names;
};

var layerInfo = getNamesPlusIDs();
for(var a in layerInfo){
$.writeln(layerInfo[a]);
}

Is this an even faster code for deleting empty layers and folders? Even the second ode version is a bit faster, it still does take a bit of time for more complex and massive psd files with tons of layers/folders......is this only a sample/partial code or is this the complete code that I can try out?

No, it is just example code that will work for Photoshop CS2 to access all the layer bounds without making the layers active.

CS2 returns layer bounds by layer ref. Line like doc.activeLayer = layer is not necessary.

I just thought than there is a method to check empty layer without access to its bounds.

The code in which post are you referring to with »doc.activeLayer = layer«?

How else make layer active?
