Basically, it's not possible: you can't "restrict" which apps can open a file (if you could, MS would use it for Word, Excel, and PowerPoint files for sure). Any app can open any file.

But ... they may not understand the content they look at - and that may be enough for you. If you encrypt your data before you write it to the file, and decrypt it when you read it, the it will certainly be harder for other apps to use.

The problem is that no matter how secure you need your data to be, remember that any app can read any file - and that does include both your data file and your application EXE file. So since your app would need to know the decryption key in order to read your encrypted data, it's a relatively simple matter to get the key from your EXE and then use it on the data files.

It's up to you to decide how "unreadable" you need your data to be and how much work you are prepared to put into it. Be aware that with any security intensive development, unless you research really well, fully understand the code you are writing / using, you can easily make your data less secure than plain text, rather than more!
