Saving data as a seperate file

I understand how to get a VB program to save data to a TXT file. What I want to know is:

- Can you get a VB program to save data to a file of your own type (eg. somefile.???)?

- If you can, how?

Thanks...

If you refering to the file extension, you can name your file extension to whatever you want.

MyTextfile.Random

VB doesn't care how you name the file, it't up to you how you handle the file.
