You can translate the question and the replies:

Extension management is empty

Following the tutorial, I thought I could select existing extensions for distributed file system (e.g. S3). However, I have no extension at all. Do I have to develop one by myself or I can download from somewhere? Thank you, M

Hi, The Denodo Express license has some limitations compared to a full license. In order to import any type of custom extensions, you should have a full license to access the Denodo Platform which imposes that importing extensions (jars) is **not allowed in Denodo express**. Hence it is not possible to develop\import custom connectors to sources, custom policies, or custom functions in the Denodo Express. To know more about the limitations of using the Denodo Express license, you can have a look at the section [Limitations of the Denodo Express License](https://community.denodo.com/docs/html/browse/latest/platform/installation/appendix/limitations_of_the_denodo_express_license/limitations_of_the_denodo_express_license#limitations-of-the-denodo-express-license) in the Appendix of the Denodo Platform Installation Guide. Hope this helps!

Hi, Thanks for the quick response. In the beginning I was trying the Express, however I am on the free trial now and I have went with the AWS image. I thought I should have full access. What do I have to do to switch the license? Thanks, Ming

Hi. For the Denodo license installation on the AWS BYOL instance you can refer to the [Denodo Platform for AWS 7.0 Free Trial BYOL - Quick Start Guide](https://community.denodo.com/docs/html/document/7.0/Denodo%20Platform%20for%20AWS%207.0%20Free%20Trial%20BYOL%20Quick%20Start%20Guide).

Thanks! I followed exactly that guide and downloaded the free trial license. I understand that with free trial there is no extension available. Only paid version does. Please confirm. Thanks, Ming

Hi, I can use the 'Extension Management' option in the free trial and I can import the jar files. Initially, there is no list of extensions. So, I developed a custom wrapper and imported it to test its functionality. In your case, If you want to use extensions for a distributed file system like S3 wrapper, you have to purchase the full license. To know more about developing custom wrapper, you can have a look at the section [Developing Custom Wrappers](https://community.denodo.com/docs/html/browse/7.0/vdp/developer/developing_extensions/developing_custom_wrappers/developing_custom_wrappers#developing-custom-wrappers) of the Virtual DataPort Developer Guide. Hope this helps!
