Hi Mark,

thanks for this, worked a treat and saved me a whole lot of 'fun' in removing copy from each layer.

Mothator,

What version of Photoshop are you using. I have a script that removes 'copy' from selected layers but it needs a document descriptor key that is CS4 or higher.

Try this. Just select the layers you want 'copy' removed from and run this script.

if( app.documents.length > 0 ){
app.activeDocument.suspendHistory('Rename selected layers','removeCopyFromSelectedLayersNames()');
}
function removeCopyFromLayerName(){
     if( getSelectedLayersIdx().length > 1 ){
          var selectedLayers = getSelectedLayersIdx();
          makeActiveByIndex( selectedLayers[0], false );
     }
   var startLoop = Number( !hasBackground() );
   var endLoop = getNumberOfLayer() + 1; 
   for( var l = startLoop;l < endLoop; l++){
        while( !isValidActiveLayer( l ) ) {
            l++;
        }
          var oldName =  getLayerNameByIndex( l );
          var newName = oldName.replace(/\scopy\s?\d*$/i,'');
          putLayerNameByIndex( l, newName )
     }
     if( selectedLayers != undefined ) makeActiveByIndex( selectedLayers, false );
}
function removeCopyFromSelectedLayersNames(){
     var selectedLayers = getSelectedLayersIdx();
     for( var l = 0;l < selectedLayers.length; l++){
          var oldName =  getLayerNameByIndex( selectedLayers[ l ] );
          var newName = oldName.replace(/\scopy.*$/i,'');
          makeActiveByIndex( selectedLayers[ l ], false );
          putLayerNameByIndex( selectedLayers[ l ], newName )
     }
     makeActiveByIndex( selectedLayers, false );
}
function getNumberOfLayer(){ 
var ref = new ActionReference(); 
ref.putEnumerated( charIDToTypeID('Dcmn'), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') ); 
var desc = executeActionGet(ref); 
var numberOfLayer = desc.getInteger(charIDToTypeID('NmbL')); 
return numberOfLayer;

Hi,

I copy'n'pasted your script into Text Edit and saved as .jsx, saved that into PS4 > Presets > Scripts and tried it but it didn't work.

I selected the layer I wanted to remove 'copy' from but got the following error.

Any possible solutions? The initial script at the top of this thread worked, but I have too many layers to work through to use it effectively.

Any help appreciated.

--cheers, matt

Thanks Michael, that did the trick!
