====""Squashfs""====
~A **""SquashFS""**(SFS) is a compressed __read-only__ file that contains files and a directory structure.  If Puppy is Frugally installed an SFS forms the base of the Puppy installation.  Extra SFS files can be loaded as additional layers.  In full installs an SFS can be decompressed and copied to the installation.  The file extension is ##.sfs##.  Often large or multiple programs are packaged in this format.

==Loading SFS software packages with a Frugal installation==
~1. The SFS package should be located at ##/mnt/home##.
---
~2. Then use one of the following methods to load the SFS:
~~-[[SFSLoad SFS Load]] (does not require re-booting) menu option at: //Menu > Setup > Setup Puppy > SFS Load//
~~-[[BootManager]] (requires re-booting) menu option at: //Menu > System > ""BootManager""//
~~-The RightClick menu option from the filer.
~~-Use terminal commands.

==Loading SFS software packages with Full installation==
~If you are using a Full Installation see [[HowtoAddSFStoFullInstall How to Add SFS to Full Installation]].

==Mounting SFS==
~If not loaded SFS files can be un/mounted and searched in ROXfiler simply by click the file in the filer window.
