How to zip files using javascript

[PinalV]

I want to zip a folder using java script. Is there a way to do it? How does the "Export for Digital Editions" do it (Since ePub is essentially a zip)?

Hi,

Try with following coding:

//----------------------------------------------
CreateZIP();

function CreateZIP(){
var fromFolder = Folder.selectDialog("Please Select The Folder to package as IDML");
if(!fromFolder)
{
    return
    }
var fullName = fromFolder.fullName;
var toZIPFile = new File( fullName+".zip" );
app.packageUCF( fromFolder, toZIPFile );
}

//----------------------------------------------

Thanks,

Praveen

app.packageUCF will work to create IDML files, but is not suited to make standard zip files. Don't ask me why, but it just doesn't work correctly with binary files.
