If you have already sent all that, it is not necessary that you take it, in the same way in the letter where you are notified of the date of the interview it says that you can take any of those documents optional.
Ok thanks for your help. This is what the letter said:
Please bring to the interview the documents, if any, listed on the second page of this letter.
Our Embassy is able to conduct interview in English, French and can provide in-house translation in Arabic. If you are not proficient in any of these languages, you will need to provide, at your expense, a certified interpreter who can interpret your language into English or French. The use of legal representatives, consultants, their employees or relatives is not acceptable as this may be a conflict of interest. As the visa officer must be satisfied that the interpreter is unbiased and qualified, interpreters are expected to provide evidence of their qualifications before the interview.
Please confirm within ten days by email whether or not you are able to attend this interview and whether you need an interpreter and for which language. If we do not appear at your interview, your application will be assessed based on the information on file which may result in the refusal of your application.
