Right Clicking A File To Open It With A .NET Program

Question

For example, if I made a compressor using the .NET Framework. How would I be able to right click a folder and open it in the compressor to compress it?

Answer 1

You need to associate file type (based on extension) with your compressor application.

For details check the article Understanding MS Windows File Associations .

It requires some registry entry modifications, that can be done from installer application.

Answer 2

Add a key under HKCR / filetype / Shell (where filetype is the filetype associated with the file extension, eg jpegfile)
