For example, should it organize files, automate a design task, or handle data compression?
Once you provide a bit more detail, I can draft a specific feature proposal or technical outline for you.
To help me "prepare a feature" for you, could you please clarify:
What is the or platform for this "Mstruku rar" feature?
Are you working on a software application, a graphic design project, or a specific game?
Did you mean "Structure" or a specific file name like "Mstruku.rar"?
