.SQF File Extension

Script created for ArmA, a series of tactical military simulation games; contains functions and commands that can be used to modify the gameplay; processed by the ArmA engine when a mission is loaded.

To activate an SQF file, you must place it in the appropriate mission directory before starting the mission. For example, \​My Documents\​ArmA 2\​MPMissions\​mod.sqf

SQF files are supported by ArmA, ArmA 2, and ArmA 3.

An SQF file is a compressed archive used by Squashfs, a read-only file system software for Linux. It stores file system data in a highly compressed, read-only format. SQF files may contain files, inodes, and directories. They are most often used to store initial ramdisks (initrd).

Some Linux and Android distributions use Squashfs to mount file systems. These file systems are compressed using either gzip, LZMA, LZO, LZ4, or Zstd compression. Squashfs is intended for only read-only file system use.

Distributions that use SQF files use the files as initial ramdisks, which are loaded as part of the Linux startup process. SQF files are not meant to be used as permanent root file systems.

NOTE: Squashfs file systems may also be saved as .SQUASHFS, .squ, or .SFS files.

You can mount and access the file system an SQF file contains using Squashfs (Linux). You can also view an SQF file's contents using 7-Zip (Windows).
