Squashfs is a compressed read-only filesystem for Linux. Typically used as a "live image" for booting Linux off a removable storage (e.g. USB, CD/DVD), minus components like the bootloader, kernel and initramfs.[2] It is also used in modern AppImage,[3], or Snap[4] as a way portable software distribution on Linux. Squashfs can also be used to store other data, such as disk images.[5] Under Windows, Squashfs contents can be opened/extracted via 7-Zip.[6]

Open a Squashfs image (as root) from present directory and have its contents visible in /mnt:
# mount example.squashfs /mnt
Open a Squashfs image (as user) from present directory and have its contents visible in /mnt/temp:
$ squashfuse example.squashfs /mnt/temp
Software
- 7-Zip
- Squashfuse (Unix-like only)
