Files with same main node but different file names

Dear all,

via FTP/FILE adapter I need to read 4 different files with different file names from a FTP server.

Unfortunately they all started with the main node named INFO but got different structures under this.

I am not able to create 4 different data types with name INFO.

Is there any other possibility to have different structures to start with same node?

Only solution I see:
- Create one big data type that include all possible subnodes. That would be tricky, because some subnodes

  got same name as well

- Create an own namespace for all data types.

Thanks
Chris
