File Systems
This page provides information on some of the file systems commonly used in Manjaro. It also shows where and how they are used. Further information on these and other file systems can be found in the ARCH Wiki
A file system manages the space on a storage medium (hard disk, SSD ...). It makes this memory available to the operating system so that files can be saved and read again. Each of the following file systems has advantages and disadvantages. They are mostly developed for a special purpose and are therefore used in a certain environment.
Linux
File systems that are mostly used under linux.
Be aware that a lot of filesystem-drivers are included into the Linux kernel. You may not need anything special to mount, read or write these filesystems. But there are packages with additional tools. You may need them to format, check, repair, modify or tune such filesystems.
Ext2 → Ext3 → Ext4
Ext4 is the default file system in Manjaro at the moment. It is the evolution of the most used Linux filesystems (Ext3, Ext2) and promises improved design, better performance, reliability, and features over its predecessors.
see Ext4@ARCH-wiki, Ext4@wikipedia
Install
In manjaro e2fsprogs is already installed
Tips
For advanced optimizations see the Archwiki Ext4 article.
btrfs
A modern file system with a lot of advanced features. Its main advantage it to be a Copy-On-Write-filesystem
see btrfs@kernel.org, Btrfs@ARC-wiki, Btrfs@wikipedia
Install
reiserfs → reiser4
This was used some time ago in a few linux distros. You may need it if you move to manjaro and have to read data from such harddisks.
see Reiser4@ARCH-wiki, ReiserFS@wikipedia, Reiser4@wikipedia
Install
pamac install reiserfsprogs reiser4progs
Windows
File systems mostly used in windows
NTFS
This today is used by most windows installs
see NTFS@ARCH-wiki, NTFS@wikipedia
Install
pamac install ntfs-3g
DOS
File systems under DOS and early windows on a lot of floppydisks and USB-sticks
FAT → FAT32 → VFAT
You may find this filesystem on disks created under DOS or Windows9x. It is sometimes used to transport files from one operating system to another.
see FAT@ARCH-wiki, FAT@wikipedia
Install
pamac install dosfstools
exFAT
Microsoft created the exFAT (Extended File Alocation Table) to make up for the inadequacies of FAT32, as it can hold large files, large numbers of files & use very large partitions. Supported on Linux, Windows, MacOS and many other devices, it is one of the most compatible filesystems. A good choice when you need to share a removable device between many systems.
see ExFAT@wikipedia
Install
pamac install exfatprogs
macOS
Filesystems mostly used in macOs
HFS → HFS+
Install
pamac install hfsprogs (AUR)
Others
XFS
see XFS@ARCH-wiki
ZFS
