PSD file size

I hope someone had this issue and was able to fix it on all his PSD file cause I have tons of file that has this bug.

Here is a variation of the metadata script that will clear the metadata from a folder of .psd files, it reduced your file to 52K:

#target photoshop

var psdFolder = Folder.selectDialog("Select the folder containing PSDs", "");

// to include jpg, tiff, and eps use this:
//var myFiles = psdFolder.getFiles(/\.(jpg|tif|eps|psd)$/i);
var myFiles = psdFolder.getFiles(/\.(psd)$/i); 

for (var a = 0; a < myFiles.length; a++){
    var docRef = open(myFiles[a]);
    cleanMeta(docRef);
};   

function cleanMeta(d){
    if (ExternalObject.AdobeXMPScript == undefined) ExternalObject.AdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");   
    var xmp = new XMPMeta( activeDocument.xmpMetadata.rawData);   
    xmp.deleteProperty(XMPConst.NS_PHOTOSHOP, "DocumentAncestors");   
    d.xmpMetadata.rawData = xmp.serialize(); 
    d.save();
    d.close();
};
