WOW 38 - FileSystem

Good Afternoon Friends,

Today I'm going to talk about Filesystems. Many may ask "Filesystem; what is that thing?". Well, heads up; you are reading this message which is stored in a Filesystem.

Filesystem means "A way of organizing files" or the hierarchical arrangement of directories. This applies to a network, a computer, a disk, or a partition (i.e., a logically independent section of a disk). A filesystem in the second sense can contain multiple filesystems in the first sense. Thus, for example, a HDD, computer or network can contain multiple types of filesystems. However, a partition can contain only a single type of filesystem.

There is a huge number of filesystem(s) available throughout. A few popular ones include:

1) Windows:

a) FAT (FAT12, FAT16, FAT32, exFAT)

b) NTFS

c) WinFS (coming up)

2) Linux:

a) EXT (ext2, ext3, ext4)

b) HPFS

c) GFS

d) XFS

3) Mac:

a) HFS

b) HFS Plus

4) Optical Media:

a) CDFS

b) UDF/ UDFS

5) GMail:

a) GmailFS/ GFS (refer: http://labs.google.com/papers/gfs.html)

Check out this Wiki page to find information about the huge number of file system and their comparison.
