What exact version/build of Alfresco are you running ?

Can you please provide more details with regards to "I am facing trouble" ? What errors do you see ?

Have you also tried connecting via the OpenCMIS Workbench ?

Also, in the future, I would recommend that you post CMIS-related questions under the "Alfresco ECM" place (and also mark it with "Public API" category), thanks.

Regards,

Jan

ps. I see your are also cross-posting similar (related ?) questions here:  Store_Type Field how to take from query?

If you just want to get the children of a folder.

You can use following methods of IFolder

        IItemEnumerable<ICmisObject> GetChildren();

        IItemEnumerable<ICmisObject> GetChildren(IOperationContext context);

To download file from Alfresco,first get the document ,the use it's GetContentStream() method,like this

      IObjectId id = session.CreateObjectId("5555555555");

      IDocument doc = session.GetObject(id);

      IContentStream contentStream = doc.GetContentStream();
