How to import a locally saved workbench/customizing request into a ECC

Hello Guys,

Long time ago I have exported a workbench and a customizing request from a development system.

Now I have to import these request to a another system (ECC 6.0) but I have no idea how to do so.

Can somebody of you give me a step by step description how to import the requests to the system?

I have 4 files.
