This file system is not included in the main list of Linux, and it is improbable for it to get there soon. However, after the incident in 2008 with main developer Hans Reiser, who went to prison, Reiser4 stopped progress. Reiser4 was the improved version that corrected lots of features and was enhanced in 2004. It was so innovative that Ext4 was incapable of implementing most of its functions. It was presented in 2001 as an alternative for Ext4.

We expect BtrFS to become equally popular in both segments of home and business usage, as it is continually developed and now is being tested. BtrFS is often considered the next and better version of Ext4. It was originally created to become an alternative to Ext series also, it has something in common with the ReiserFS former default file system for Linux. This file system involves drivepool, automatic snapshot, transparent compression, and availability for online defragmentation. It had lots of updates and work put in it, so it is widely popular.ītrFS usually stands for B–Tree File system, but is pronounced as ‘better’ or ‘butter’ FS. It is a basic or default version of the file system on Linux, nowadays. It was enhanced and involves fresh updates that reduced file fragmentation, made it possible to have larger files and sizes, and has a delayed allocation, which is profitable for flash memory duration. The one has a built–in Ext4 file system, as Ext3, Ext2, and backwards. So, compared to Ext3, Ext4 is better in use.Įxt4 and Ext3 were created for compatibility reasons. It is quite an old and usable version, but Ext4 is more common and stable. It was created to be backwards connected with Ext2, so partitions between Ext2 and ext3 were able for conversion with no formatting. So, if you don’t need Ext2, it is better to pay attention to rather modern similar file systems.Įxt3 is similar to Ext2, but it includes journaling. They are more usable with various OS and are comfortable. However, more universal advanced file systems are available nowadays, like exFAT or FAT32. Ext2 absence of journal makes it comfortable to use on portable flash drives.

When it was presented, its modernity was that it supported extended file attributes and 2 terabyte drives. It is far from perfect, so lots of Linux distributions no longer support Ext.Įxt2 does not support journaling.

It was presented in 1992 and was a massive update from Minix file system. It was the first system created for Linux.
