In this project you will be designing and implementing a file manager application, in the C programming language. The most important feature of your file manager will be such that you should be able to use it on top of any operating system that has a standard C compiler installed. Hence, you should NOT use any operating systems commands (shell commands, utilities, etc.), nor any system calls in your project. All calls in your program must be towards standard C functions, and towards the standard libraries. Your program should must provide the following functionalities: Create a new file. Delete an existing file. Rename an existing file. Copy a file. Move a file from one folder to another. For text files: o Append text to the end of a file, o Insert text in a specific position within the file (positions should be counted in number of characters), o Remove all text present in a file, o Show the content of a text data store, with the ability to pause per page. The number of lines per page could be specified by the user. Your program should support commands to be executed by its users to carry out the tasks specified above. All of your commands should have a help' feature. If the user types command /h for example, the program must illustrate the usage of the command
