The Linux file structure is organized in a hierarchical manner, starting from the root directory /. Here are the key folders under the top-level directory:

Directory	Purpose
`/`	Root of the file system; the starting point.
`/root`	Home directory for the root (superuser).
`/bin`	Essential binary commands.
`/sbin`	System administration binaries.
`/etc`	Configuration files for services and applications.
`/home`	User home directories.
`/dev`	Device files.
`/var`	Variable data such as logs and cache.
`/proc`	Runtime system process information.
`/usr`	User-level applications and binaries.
`/opt`	Optional third-party applications.
`/mnt`	Temporary mount point for external file systems.
`/media`	Auto-mounted removable media.
`/boot`	Stores boot loader files, including the kernel and other files needed to boot the system.
`/lib`	Shared library files that are used by the binaries in `/bin` and `/sbin`.
`/run`	Contains runtime data for processes and applications. This directory is used for storing temporary data that is needed during system operation.
`/sys`	Contains system information and configuration files. This directory is used for interacting with the kernel and hardware.
`/tmp`	Temporary files. This directory is used for storing files that are needed temporarily and can be deleted after use.
