Disk filesystems

 * ext4 - The default, GPL licensed journaling filesystem for many Linux distributions.
 * JFS - A GPL licensed, 64-bit journaling filesystem developed by IBM.
 * Btrfs - A copy-on-write B-tree filesystem with advanced features.
 * NTFS - Microsoft Windows default filesystem.
 * Aufs
 * OverlayFS
 * SquashFS - A compressed read-only file system for Linux
 * XFS - A GPL licensed, 64-bit journaling filesystem created by Silicon Graphics.
 * ZFS - A CDDL (non-GPL compatible) licensed, copy-on-write filesystem created by Sun Microsystems.

Virtual filesystems

 * procfs - Used to output and change of system and process information.
 * sysfs - Used to output information about and to configure devices and drivers.
 * tmpfs - Used to store files in memory (RAM).
 * devtmpfs - requires devtmpfs (Maintain a devtmpfs filesystem to mount at /dev) in the kernel.

Network filesystems

 * Ceph - A distributed object store and filesystem designed to provide excellent performance, reliability and scalability.
 * NFS - A common Linux network file system protocol.
 * SSHFS - Implements FUSE to mount filesystems in user space.
 * TahoeLAFS - A least authority file system.

Mounting
Filesystems can be mounted in several ways:


 * - The command used to manually mount filesystems. Requires administrative privileges or entries in.
 * fstab - Contains descriptive information about the filesystems the system can mount.
 * Removable media - Mount on file demand.
 * AutoFS - Automatic mount on file access.
