Aspose.Zip only archiving 10 items

In testing various methods for archiving files using Aspose.Zip for .NET, I have noticed that only the first 10 items are actually archived. For example, it may archive only 10 of 20 files added using archive.CreateEntry. Similarly, the archve.CreateEntries method will only archive 1 folder and 9 files, despite there being many more folders and files in the collection.
Is there something I am missing?

Hello @jburnett,
This happens because of limilations of trial version .
If you want to test Aspose.ZIP without evaluation version limitations, you can request a 30 Day Temporary License.

Hi Eugene,
Thanks for the information. I have a 30 Day Trial licence, which is why I was confused. However, when I checked, I realised I had forgotten to set the licence in the relevant bit of code!
