ext3: Most commonly used file system with Linux. Contains journaling features for safer data and fast reboots after unintended shutdowns.

ext2: Predecessor of ext3, but doesn’t contain journaling.

iso9660: Evolved from the High Sierra file system (which was the original standard used on CD-ROM). It may contain Rock Ridge extensions to allow iso9660 file systems to support long file names and other information (file permissions, ownership, and links).

Jffs2: Journaling Flash File System version 2 (JFFS2) that is designed for efficient operations on USB flash drives. Successor to JFFS.

jfs: JFS file system that IBM used for OS/2 Warp. Tuned for large file systems and high-performance environments.

msdos: MS-DOS file system. Can be used to mount older MS-DOS file systems, such as those on old floppy disks.

ntfs: Microsoft New Technology File System (NTFS). Useful when file systems need to share files with newer Windows systems (as with dual booting or removable drives).

reiserfs: Journaling file system that used to be used by default on some SUSE, Slackware, and other Linux systems. Reiserfs is not well-supported in Fedora or RHEL.

squashfs: Compressed, read-only file system used on many Linux live CDs.

swap: Used on swap partitions to hold data temporarily when RAM is not currently available.

ufs: Popular file system on Solaris and SunOS operating systems from Sun Microsystems.

vfat: Extended FAT (VFAT) file system. Useful when file systems need to share files with older Windows systems (as with dual booting or removable drives).

xfs: Journaling file system for high-performance environments. Can scale up to systems that include multiple terabytes of data that transfer data at multiple gigabytes per second.
