You may find other filesystem like:
tmpfs: a common name for a mounted file system, but stored in volatile memory instead of a persistent storage device
drvfs: mounted Windows disks, seen in Windows Subsystem for Linux (WSL). e.g.
$ cat /proc/partitions major minor #blocks name 253 0 31457280 vda 253 16 62914560 vdb 253 32 65536 vdc 253 48 251658240 vdd
file -s <device> to check type
$ sudo file -s /dev/vda /dev/vda: Linux rev 1.0 ext4 filesystem data, UUID=6f54f78f-3f47-488c-ab1b-b1b8a596c2d3, volume name "c3image-rootfs" (needs journal recovery) (extents) (large files) (huge files)
FUSE: Filesystem in Userspace. The interface that lets non-privileged users create their own file systems without editing kernel code; a "bridge" to the actual kernel interfaces. E.g. GlusterFS, GmailFS.
- macOS/iOS: APFS, Apple File System
- replaces HFS+
- optimized for flash and solid-state drive storage, with a primary focus on encryption
- APFS supports 64-bit inode numbers, supporting over 9 quintillion files on a single volume
- Windows 10: NTFS
- Red Hat/CentOS: XFS
- gvfs: GNOME Virtual file system. GNOME's userspace virtual filesystem.
/dev/shm: an implementation of traditional shared memory concept, i.e. passing data between programs. One program will create a memory portion, which other processes (if permitted) can access. This will result into speeding up things on Linux.
tmpfs: a temporary file storage paradigm implemented in many Unix-like operating systems, overcomes many of the drawbacks with
ramfs. It is intended to appear as a mounted file system, but data is stored in volatile memory instead of a persistent storage device.
