psd文件图层不多却很大很卡

1. 打开PS 「 文件」——「 文件简介」——「原始数据 」当中，查看该文档是否有过多没必要的信息。图中展现的原始数据当中，有上千条 信息。

2. 新建一个txt文件,将下面代码复制进去,然后将文件保存为jsx文件格式

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(); 

3. 用PS打开文件比较大的PSD文档，「 文件」——「 脚本」——「 浏览...」选择刚刚保存的 Jsx 格式文件即可解决
