Hi,

I'm evaluating xceed zip Real Time to decide if it fits our needs.

 I have a large amount of files (inside a folder with subfolders) to zip - deflate normal compression and encrypt - AES 256 

What's the FASTEST method

1 - encrypt and compress on the fly to a ZIP file

2 - create a no compressed (storage method) and no encrypted zip and then compress and encrypt the zip file (so it will be a zip inside a zip)

I'm using this code below (vb.net example) with minor changes

Thank you 

Hi John,

The fastest method would be the first one, because "On the fly compression" means compressing without using temporary files (or any other temporary storage); this is what makes our Real Time Zip component faster than our Xceed Zip for .NET when it comes to creating entirely new Zip files.

Of course, you can try this by urself and confirm my answer.

Regards,
