Linux uses a unified filesystem structure that complies with the filesystem hierarchy standard, which, while not always immediately intuitive, is designed to make it an easier task of locating specific files on the system manually, and also to allow software written for it to be able to predict where its needed files are kept.
When selecting a file organization method, it is important to consider factors such as access speed, ease of organization, security, and scalability. Access speed refers to how quickly data can be retrieved from the file system, which can be influenced by the organization method used. Ease of organization involves how easily files can be stored and retrieved in a logical manner. Security considerations include protecting data from unauthorized access or loss. Scalability is important for ensuring that the file organization method can accommodate a growing amount of data without compromising performance.
In Linux the chmod command is used to set file permissions.
The Linux Filesystem Hierarchy is used to help determine the file structure in the Linux Operating System. It defines the Directory structure and directory contents.
The unknown compression method used in this file is not specified or identified.
The Linux VFS (Virtual File System) may be thought of as a sort of interface between the Linux kernel and the mounted file systems. There can be many different file system types mounted simultaneously and VFS allows the Linux kernel to see and address them all in a similar way. This provides Linux with a great deal of flexibility. [JMH]

Need to be more specific in your question.
touch newfile will make a new empty file in linux os !
It means that the file or directory is used for application settings.
NFS provides a method for accessing remote file systems over a network. This can be used for multiple purpose, including unified logins and diskless thin clients.
in terminal it is : #cp file_a file_b
