That's no way to introduce yourself. You got the same type of brain that I have, and you probably run on water and sunlight like the rest of us. Use a database (like SQL CE or SQLite), encrypt the contents and rename the extension to ".dat". Use a folder, zip it and rename the zipfile to ".dat". Use an Xml file, and store the other files in Base64-encoding, and rename it to ".dat". Let's start simple; can you post the code here to write the line "Hello world" to a file? If not, that's where to start :)

These select quotes from the thread of yours @ MSDN says it all:

Why don't you simple say, don't say what should I do, just make and sell it for me and give me the money.

"Use a zip file and change the extension" That does not help you? That is quite a common way nowadays. Ever tried it the other way round, with say a .docx? Do that! Rename a Word document to a zip file, and unzip it!

If you want to do it through your own code, use a FileStream to read the files into memory and another to write them to the same file. FileStreams read the raw bytes of the files. You'll want to put some sort of delimiter between the files so you can separate them later. To add your delimiter to the file, create a string and then use System.Text.Encoding.Ascii.GetBytes(YourStringVariable). That will give you a byte array with which to write with the filestream's write method. Hope that wasn't too confusing!
