Upon installation, Linux offers numerous file systems just like the ones below that you simply will choose from:

  •      Ext
  •      Ext2

  •      btrfs
  • swap


File System For Linux

Ext 1: 

“ext 1” is an associate degree form that stands for “extended filing system” and was designed and developed in 1992 and is that the terribly 1st file system designed specifically for Linux. Its practicality was designed to part support the Linux filing system. The aim of its creation originally was to initiate on the far side the filing system used before it (the MINIX file system) and overcome its limitations.

As this filing system is regarding thirty years previous at the time this text was written, several Linux distros do not support it. Thus it is not extremely used any longer.

Ext 2: 

additionally remarked as “second extended system.” Designed and developed in 1993, ext2 was created to be the successor of the first extension system for Linux.

It innovated in areas like storage capability and general performance. This filing system notably permits for up to a pair of TB of information. Like ext, this filing system is extremely previous; thus, it extremely ought to simply be avoided.

Ext 3:

 ext 3, or the third extended system, was developed and designed in the year 2001, surpasses ext2 in this it is a journaling filing system. A journaling filing system may be a system that records during separate log changes and updates to files and information before such actions are completed.

This means that if for a few reasons, the pc or exhausting disk(s) crashes or expertise some reasonable power outage, this separate log containing the changes created before the crash will be wont to access that hold on information, therefore, repairing and restoring the files upon revive.

Nowadays, there are such a huge amount of higher choices to settle on that there’s hardly any reason to use this extended filing system any longer either.

Ext 4:

 ext 4, standing for “fourth extended system,” was created and designed in 2006. as a result of this filing system overcomes various limitations that the third extended system had; it’s each wide used, and therefore the default filing system that almost all Linux distros use.

While it should not be the foremost innovative, it is completely reliable and stable – which is actually valuable in Linux.

Thus, if you are not notably keen on painful your brain between the various execs and cons of all the numerous file systems you will be able to select from, we have a tendency to positively suggest you simply come with this one.


The filing system JFS was created by IBM in 1990, and therefore the name JFS is associate degree form standing for Journaling filing system; as we have already lined this idea with the quantity three filing system during this article, you ought to already be quite at home with what precisely this implies.

It is straightforward to recover information once an influence failure and quite reliable. What is additional is it uses less central processor power than the other opposite file system


 xfs, associate degree form that stands for “Extent File System”, was created by semiconductor Graphics and originally created for his or her OS “IRIX”; however, it was later given to Linux.

Developed and designed in 1990, XFS may be a 64-bit high-performance journaling filing system. It is notably noteworthy for the way implausibly well it works with terribly giant files. Through contrarily, not particularly the best with smaller files.


btrfs, that is yet one more form standing for B Tree filing system, created by Oracle in 2009. It is considered a rival filing system to ext 4, through it is agreement that overall ext4 is that the higher filing system, because it transfers information quicker and offers additional stability however though this is often the case, that doesn’t mean btrfs is not priced trying into.

There are a few things that are distinctive and advantageous regarding btrfs. And normally, it is a glorious performance.

If you could not tell already from the comparisons created in our list, ext 4 is and is considered the simplest Linux filing system.
