Architecture Overview

The following things will be present in the application:

Section 1:

This is the region outside the disks. From here you will create a disk and then mount/open it to perform all basic operations mentioned in section 2.

• create disk: Creates an empty disk of size 500Mb. While creating an empty disk a unique name will be given to it which will be used to mount it.
• mount disk: Opens the specified disk for various file operations. As mentioned in section 2.
• exit: Close the application.

Section 2:

This is the region inside the disk. You may have multiple disks. You will open only 1 disk at a time. After opening/mounting a particular disk, you will perform below mentioned operations in the disk:

• create file: creates an empty text file.
• open file: opens a particular file in read/write/append mode as specified in input, multiple files can be opened simultaneously.
• read file: Displays the content of the file.
• write file: Write fresh data to file(override previous data in file). Type exit() to come out from the mode.
• append file: Append new data to an existing file data. Type exit() to come out from the mode.
• close file: Closes the file.
• delete file: Deletes the file.
• list of files: List all files present in the current disk.
• list of opened files: List all opened files and specify the mode they are open in.
• unmount: Closes the currently mounted disk.
