为什么PSD中没有几个图层却占用几个G空间？

1、将下面的代码，复制粘贴到文本文档中，存储为.jsx文件（就是把扩展名为.txt结尾的文档，改成 .jsx文档）

function deleteDocumentAncestorsMetadata() {

whatApp = String(app.name);//String version of the app name

if(whatApp.search("Photoshop") > 0) { //Check for photoshop specifically, or this will cause errors

//Function Scrubs Document Ancestors from Files

if(!documents.length) {

alert("There are no open documents. Please open a file to run this script.")

return;

}

if (ExternalObject.AdobeXMPScript == undefined) ExternalObject.AdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");

var xmp = new XMPMeta( activeDocument.xmpMetadata.rawData);

// Begone foul Document Ancestors!

xmp.deleteProperty(XMPConst.NS_PHOTOSHOP, "DocumentAncestors");

app.activeDocument.xmpMetadata.rawData = xmp.serialize();

}

}

//Now run the function to remove the document ancestors

deleteDocumentAncestorsMetadata(); 

2、打开有问题的psd文档，执行｛文件｝－｛脚本｝－｛浏览｝命令，找到刚刚建好的jsx文档打开，稍等几秒即可完成处理。

3、ps文档直接保存即可，以后再操作起来，你会发现ps不止快了一点点哦～
