Take your IDAT files, and follow the guide of a tool such as minfi

I need to know what are these files ,"Table Control...",... In the minfi package, there is not any information about these files.

I imagine they're control probe information, information on hybridisation efficiency, bisulphide conversion, etc. You don't need to use them, the IDAT files are the truly raw data from the scanner, and it's what pipelines such as Minfi use as inputs.
