I need to import these two different types of files. They are files used to describe a dataset created with the old version of rapidminer, it was called YALE.
Not directly. You may try to read the .exa file using the csv import wizard. Most likely this file will be a standard text file containing all the values of a table row in one line separated by a space character. Adding the attribute names from the .att file requires some search-and-replace efforts inside a text editor to extract a text row containing all names which you can add as first row to your data file.
