recieve folder or file name

Then you should clarify what you mean by "Windows Context menu". How did you do that? Where in the documentation is it described?

Perhaps it is a file type association that you created. If so then the file type association specifies what the arguments are.

Do you know that "command-line" arguments are pased from Windows to a program as arguments for the Main function?

I mean for example how winrar understands that what folder should be compressed when I right click on a folder and run winrar?

I am not sure what you are asking. Do you need to know how to get a parameter from a command line or are you asking how to specify a folder to be used as a parameter? If the "Windows Context menu" is the Start menu and you need to be able to specify a folder to be used as a parameter when executng from that then it is not possible.
