Create hooks for Windows desktop application-2

I need someone to create the following hooks for a windows desktop application: Step 2 Creating a prototype of hooks for watching a specific file's actions and modification and opening and closing. - Create hooks for: -when a file/folder is opened -when a file/folder is closed -when a file/folder is modified - For each hook, a msgbox box should appear with a different msg for different hooks. - Repeat above implementation in 6 ways: (1) For all files in file system. (2) For files with particular extension only, such as .txt files. (3) For a particular file in a particular location only. (4) For all folders in file system. (5) For a particular folder in a particular location only. (6) For all files/folders in a particular location. - Implementing this more efficiently as compared to repeated watch on file over and over is important in order to conserve CPU cycles. This is a step of a larger project, whose entire description I have attached. You would be hired to implement just this particular step, and will be paid right away after the completion and testing of the work. If you are successful, you might be hired for the rest of the project. This project is for a trusted client. No milestones or upfront payments will be created until the project is completed, and tested by the client, and until the client is happy. Whoever bids $100 or less will be hired immediately.
