Photoshop scripting mantain same file name and whitespace - photoshop-script

Question

I'm trying to add a layer to some images and then save them.
The problem is that many images have whitespace in the name. When I try to save the whitespaces are replaced with "-", but I want mantain the same name.
For example an image called "Google Analytics.png" become "Google-Analytics.png". But I need to preserve the name without that extra "-".
My code:
function SavePNG(saveFile){
var file = new File(saveFile);
var pngOpts = new ExportOptionsSaveForWeb;
pngOpts.format = SaveDocumentType.PNG
pngOpts.PNG8 = false;
pngOpts.transparency = false;
pngOpts.interlaced = false;
pngOpts.quality = 100;
$.writeln(file)
app.activeDocument.exportDocument(file,ExportType.SAVEFORWEB,pngOpts);
}

Try using saveAs instead of exportDocument; it'll respect the name of the file you give it. The options are yours to change:
var myfile = "C:\\temp\\Google Analytics.png";
SavePNG(saveFile)
function savePNG(saveFile)
{
// save out the image
var pngFile = new File(filepath);
pngSaveOptions = new PNGSaveOptions();
pngSaveOptions.embedColorProfile = true;
pngSaveOptions.formatOptions = FormatOptions.STANDARDBASELINE;
pngSaveOptions.matte = MatteType.NONE;
pngSaveOptions.quality = 1;
activeDocument.saveAs(pngFile, pngSaveOptions, false, Extension.LOWERCASE);
}
