How do I assign an extension e.g. *.ttt to a program with a *.REG Registry file ?

[Wolfgang Hercker]

Assume I have files with a new or already existing extension *.ttt.

Now I want to always open these types of files with a new program e.g. D:\testprgm\myprogram.exe

How can I assign these extension to the program in the registry ?

No, I don't want to do this through WindowsExplorer (Folder Options->File Types) or any other
GUI based program.

After the assignment whenever I click on files with this extension the files should automatically opened
with the mentioned program.

It should be done directly in the Registry resp. with a *.reg file.

Furthermore I want to assign files with NO extension to this program as well.

If I assign this manually to the "Unknown" file type it doesn't work.

Add the new extension via Folder Options (File Types dialog) or via the
registry directly. Then export the appropriate branch to a .REG file, which
inturn can be deployed in other systems.
