1、你可以在「 文件」——「 文件简介肝捐错暄」——「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，有上千棰很于秋条 <rdf:li> </rdf:li> 信息。这些正是拖慢我们保存文档速度与文档「 膨胀」的元凶。
2、将下面这段代码复制粘贴到文本文档中，另存为 Jsx 格式文件。function deleteDocumentAncestorsMetadata() {whatApp = String(app.name);//String version of the app nameif(whatApp.search("Photoshop") > 0) { //Check for photoshop specifically, or this will cause errors//Function Scrubs Document Ancestors from Filesif(!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 ancestorsdeleteDocumentAncestorsMetadata();
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。
