In this project, we create a file in C programming language, which we will call isu_filemanager from now on. You will design and implement the manager application. The most important feature of your file manager, you can use it on any operating system that has a standard C compiler will be. Therefore, any operating system commands ('shell' commands, 'utility' programs, etc.) or system calls. All calls in your schedule, should be done towards standard C functions and standard libraries. Your program should perform the following functions:  Creating a new file.  Deleting an existing file.  Rename an existing file.  File copy.  Moving the file from one folder to another.  For text files:  Adding text to the end of the file,  Adding text to a specific location in the file (locations are as number of characters should be counted)  Remove/delete all text in a file,  Show the content of a text file with pause per page feature. Page The number of rows per line must be user definable. Your program is created by its users to perform the above-mentioned tasks. It must support a set of commands that can be run. All your commands have a 'help' property and, for example, if the user types command_name /h, the program should show the use of the command. All your commands e.g. file does not exist, filename already exists, invalid command etc. as exceptional and should be ready to deal with faulty situations, and in such cases prompt the user with the appropriate message. should warn. You can give any naming to your commands.
