Design

So, I have used Trie for implementing the File system, a node of a trie represent and entity, and an entity can be a file/directory. A node of trie contains :

        name(name of the file/directory)
        children(a map of all the files/directories that a directory contains)
        isDirectory( as the name suggests its a flag to differentiate between file and directory)
        fullPath( full path relative to the root folder)
        content( contents if the entity is a file)

Every entity has a children ".." which points to the parent except root. This child is added when we create an entity with command like touch and mkdir.
