What Filesystem Does Linux Use?
Contents

Linux supports numerous file systems, but common choices for the system disk on a block device include the ext* family (ext2, ext3 and ext4), XFS, JFS, and btrfs.

What is the default file system in Linux?

The big file system news in Red Hat Enterprise Linux 7 beta is that XFS will be the default file system for the boot, root, and user data partitions. Naturally, the existing ext4 file system (the default in Red Hat Enterprise Linux 6) will be fully supported, along with the earlier ext variants (ext2 and ext3).

What filesystem does Ubuntu use?

We’re talking about four main file systems: Ext2/Ext3/Ext4 and Btrfs (see B-Trees) as Ubuntu natives, and FAT32 and NTFS on Windows. There are other options such as ReiserFS, but this FS is being deprecated and has been dropped from other Linux distros such as OpenSUSE.
