I want to make a program that runs as a service and changes the folder icon based on its foldercontent, like svn does. And I also want to change the icon and the behavior of a folder if the name is example.someextension .
How may I programmatically achieve this and which namespaces or libraries could do that?
You can try to use:
DirectoryInfo, Directory to get directory name, subdirectories, files in directory.
Tutorial to learn how to create windows service.
And this question to change folder icon.
Good luck
