ZipFileReader class can NOT make directory or file.
So you should make directory or file according to ZipEntry.isDirectory() method.

var file:File = File.desktopDirectory.resolvePath("sample.zip");

var reader:ZipFileReader = new ZipFileReader();
reader.open(file);
var fileList:Array = reader.getEntries();
var baseDir:File = File.documentsDirectory();

for each(var entry:ZipEntry in fileList){
	var filename:String = entry.getFilename();

	if(entry.isDirectory()){
		//  If entry is directory
		var dir:File = baseDir.resolvePath(filename);
		dir.createDirectory();
	}
	else{
		var unzippedBytes:ByteArray = reader.unzip(entry);
		var file:File = baseDir.resolvePath(filename);
		var fs:FileStream = new FileStream(FileMode.WRITE);
		fs.writeBytes(unzippedBytes,0,unzippedBytes.length);
		fs.close();
	}
}
reader.close();

var zipReader:ZipFileReader = new ZipFileReader();
zipReader.addEventListener(ZipEvent.ZIP_DATA_UNCOMPRESS,uncompressData);
zipReader.open(file);
var entries:Array = zipReader.getEntries();
for(var i:int = 0; i<entries.length; i++){
     var entry:ZipEntry = entries[i] as ZipEntry;
     zipReader.unzipAsync(entry);
}

sample unzipAsync event handler
( save file )

private function uncompressData(e:ZipEvent):void{
    var entry:ZipEntry = e.entry;
    var file:File = dir.resolvePath(entry.getFilename());
    var fs:FileStream = new FileStream();
    fs.open(file,FileMode.WRITE);
    fs.writeBytes(e.data);
    fs.close();
}

The last time I introduced the features of “Airxzip”, this post says one of the features.

Change file system and set filemode and directory mode

var writer:ZipFileWriter = new ZipFileWriter(ZipFileWriter.HOST_UNIX);
writer.open(File.desktopDirectory.resolvePath("airxzip_unix.zip"));

writer.setDirMode("0700");
writer.setFileMode("0700");

writer.addDirectory("Foo1");
writer.addFile(File.desktopDirectory.resolvePath("image.jpg"),"Foo2/image.jpg");

writer.setFileMode("0766");
writer.addFile(File.desktopDirectory.resolvePath("image.jpg"),"Foo3/image.jpg");
writer.close();

Default filetype is “ZipFileWriter.HOST_WIN”.
So If you want to create zip file for Mac or Unix/Linux , Please set “ZipFileWriter.HOST_UNIX”.

var writer:ZipFileWriter = new ZipFileWriter(ZipFileWriter.HOST_UNIX);
