Folders and text files

I have a program that uses a lot of loading/saving of text files, and I want some of these files to be unreadable to the user. I gave them weird extensions like .crse, but what I'd really like to do is make the files hidden or not readable in notepad. I guess I could encrypt them, but that would take a while, and my code is already messy. Also, with all of these files, my folder becomes really cluttered, is there a way for me to make new folders? Lastly, how do I delete folders and text files. Thanks in advance.

1. To make it unreadable, you can write it in binary.

2. not sure

3. I know there is a C function called remove in stdio.h, not sure about the C++ function.

What is binary and how would I implement it?

Oh never mind thats the 1001011 stuff, but is there a function to do it for me? Otherwise it will be just like encryption.

binary... isn't that put in hex form like FF, EE, CD, 08,... ?


I prefer encryption. Encryption in binary is even better. Otherwise, your output can still be read using hex viewers...

Fine, I guess encryption is the easiest way, but does anyone have an answer to my other questions?

The easiest way is to do it in binary. Though I do lots of windows programming I've never actually learned file i/o using windows functions so this will have to do.
#include <fstream.h>

ifstream ifile; //input stream
ofstream ofile; //output stream

void main()
{
ifile.open("file.myfile", ios::in | ios::binary);

}

void main()
{
unsigned int whatever;

// if you want more info look in the msdn or message me or
// something
ifile.open("file.myfile", ios::in | ios::binary);
ifile.read((unsigned char *)&whatever, sizeof(unsigned int));
ifile.close();
}

You can use
system("mkdir mydirname");
to make a directory and
system("rmdir mydirname");
to remove a directory
system ("attrib myfilename.txt +h");
will hide the specified file.]

You might have to include windows.h to use system.. but I'm not sure.

From stdlib

system ("attrib file.dat +h")

**Edit*** Doh! Beat me to it... damn telephone calls.

is it possible that if you have the binary/hex code (3B 6Y GB) for a program, you can copy and paste the hex into your c++ code and output it into the machine code mess?

for example,

outputfile << "3E 4E 7K bal bal bal ablab....";
and use ios::somthing that makes it into machine code instead of binary?

The compiler won't understand it unless there is some structure like _asm is for assembly language. And by the way the alpha characters in hex codes only go A-F.
