Conventional File Systems

HFS
Used by Apple systems, it has been succeed by HFS+.
ffs
The Fast File System, a variant of ufs that is faster and supports symbolic links.
ext2, ext3
ext2 was introduced with Linux. ext3 is a journaled version of ext2 which allows for speedy disk recovery after a crash.
reiserfs
A journaling filesystem for Linux.
FAT
Originally used by MS-DOS. Includes FAT12 (for floppy disks), FAT16 and FAT32.
NTFS
The New Technology File System, introduced by Microsoft with Windows NT 4.0. Now used on Windows XP.
ufs
The Unix File System, introduced with Unix.

Cryptographic File Systems

Cryptographic file systems encrypt information before it is stored on the media. Some of these file systems store encrypted files directly. Others are better thought of as device drivers, which are then used to store some of the file systems discussed above.

File Vault
A clever user interface to Apple's encrypted disk images. Uses the ".sparseimage" extension on disk files.
CFS
Matt Blaze's Cryptographic File System for Unix.

TCFS
Transparent Cryptographic File System.
