In CentOS 7, the hidden file on the hard drive used to hold parts of programs and data files that do not fit in memory is called "swap". This acts as virtual memory and allows the system to continue running even when physical memory is running low. Caches and buffers are also used to improve system performance, but they are not specifically used to hold data that does not fit in memory. Therefore, the best choice is D - swap.
