Zipping

To compress an entire directory into a zip file you use the zip() function.

The extension will dispatch one of two events to determine the result of the unzip:

• ZipUtilsEvent.ZIP_COMPLETE: Indicates the zip is complete and the zip file is available
• ZipUtilsEvent.ZIP_ERROR: Indicates there was an error zipping the file

There is also a progress event that will be dispatched at intervals. Depending on the operating system but generally after each file is added to the zip.

Example

ZipUtils.service.addEventListener( ZipUtilsEvent.ZIP_COMPLETE, zipCompleteHandler );
ZipUtils.service.addEventListener( ZipUtilsEvent.ZIP_ERROR, zipErrorHandler );
ZipUtils.service.addEventListener( ZipUtilsProgressEvent.PROGRESS, progressHandler );

var zipFile:File = File.applicationStorageDirectory.resolvePath( "example.zip" );
var sourceDir:File = ...; // Some directory to zip

ZipUtils.service.zip(
        zipFile.nativePath,
        sourceDir.nativePath
);

Event handlers:

private function zipCompleteHandler( event:ZipUtilsEvent ):void
{
    trace( "zip complete" );
}

private function zipErrorHandler( event:ZipUtilsEvent ):void
{
    trace( "zip error" );
}

private function progressHandler( event:ZipUtilsProgressEvent ):void 
{
    trace( "progress: " + event.bytesLoaded +" / "+event.bytesTotal );
}
