    I don't understand what codesys want me to do I tried do declare a variable for USB_STORAGE_HANDLER and it's still not working (I don't want it to work with a function block i want that to work in ST)

    Copy_Device_To_USB is a function block and must be declared. So in your VAR section you would do something like:

    VAR
       FB_CopyDeviceToUSB:  ifmFileUtil.Copy_Device_To_USB;
    END_VAR
    
    //Then call FB_CopyDeviceToUSB to access function block
    FB_CopyDeviceToUSB(.....);
    

    Hope this helps.
