Delete files below 10 kb

[HundeVadT]

Hi Adobe fans

how do i delete small images in a folder ?

var folder = Folder.current;
var files = folder.getFiles("*.png");
for (var f = 0; f < files.length; f++) {
     if (files.size < 10000 ){
          alert(files.name +" deleted ")
          files.remove();
     }
}

According to the OMV, it doesn't appear that file size is available to us.. I looked through all the available properties and methods and nothing points in that direction.. I also tried some 'common sense' options that aren't listed and none of those worked either.

Is there some specific reason that you want to do this task from illustrator? It sounds like a task better suited for a shell script.

My script is create images files from the layers "png files"

But when a layer is empty it create a small black square png image.

can I make a: if a layer is empty don't run the export function?

So your script exports each layer as a PNG, then you want to retroactively go back and delete any PNGs that were exported from empty layers?

Can you share the script that you're using so i can try to make some suggestions? My inclination is that you should check to see if a layer is empty before exporting it, rather than exporting it and then deleting it later.

The File.length property shows your the file size.

ah, yes. of course... because calling that property "size" or "fileSize" would have been confusing. instead, let's go with a name that's almost always used to denote an integer count of elements in an array.

var options = new ExportOptionsPNG24();

options.horizontalScale = 400;

options.verticalScale = 400;

options.antiAliasing = false;

options.transparency = true;

if (document && folder)

parseLayer(document, "", 1);

function parseLayer(layer, base, depth) {

alert

var popups = [];

var takeShots = true;

log(depth, "parsing " + layer.name);

for (var i = 0; i < layer.layers.length; i++) {

var l = layer.layers;
