Generally, Denodo Platform is capable of connecting to any data source using various access machanisms like JDBC, ODBC,JSON, Excel etc;. If you are looking for some custom connector like Denodo Distributed File System Custom Wrapper, FileSystem Custom Wrapper etc; then you can download them from the Denodo Support Site under “Downloads > Denodo Connects” option if you have a valid Denodo Support account. Also you can develop your own custom component using [Denodo4E](https://community.denodo.com/docs/html/browse/7.0/denodo4e/index) plug-in for Eclipse.
For more details, you can refer to [Creating Data Sources and Base Views](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/creating_data_sources_and_base_views/creating_data_sources_and_base_views) section of the Virtual DataPort Administration Guide.
Hope this helps!
