You mean in your C: drive? How could anyone but yourself tell it?
Data files for what? The system? Undoubtedly that'd be the system32 folder, but your best bet, look in the C:\WINDOWS\ folder for all of them.

ASCII and BINARY are the basic classifications of files
Data files are data whereas data records are backups.
If you have a D drive on your computer, then you can save files onto it. You might do so to have your data files on a particular drive, rather than having them all on the C drive. Your C drive is usually used for storing the actual programs. So it can be useful to keep your data on a separate disk. It is a good organisational strategy. It can make it easier to see how much data you have, as you know that anything that is on the D drive are data files. If there is a crash on the C drive, you could still have all your files safe on the D drive. So there are lots of good reasons for doing it.

As far as C++ is concerned files do not have structures, they are simply raw data streams. It's entirely down to the programmer to determine what structures exist within the file and to interpret the data accordingly. C++ cannot do it for you.
A struct file in computing typically refers to a structured representation of data, often used in programming languages like C or C++. It allows developers to group related variables, known as members, under a single data type for easier management and manipulation of complex data. Struct files can also refer to files that contain structured data, such as JSON or XML, which are used for data interchange between systems.
That would include header files, data types, loops, functions, pointers, arrays
