What is a .SQFS file?
The file extension .SQFS refers to a Squash FS Bootable File. This type of file is essentially a bootable disk image used primarily in Unix-based systems. It functions similarly to a physical disk, which means it can be mounted and accessed as if it were an actual hard drive connected to the computer.
The .SQFS file is formatted using the Squash FS file system, which is known for its ability to compress files in a read-only format. This compression helps in saving space while ensuring the files are securely stored without the ability to modify them, which is particularly useful for maintaining the integrity of the system files.
These .SQFS files are commonly utilized for distributing and installing operating system files. For example, when setting up a new Linux system, a .SQFS file might contain all the necessary files for the installation. This is often seen in scenarios where a Linux LiveCD is used. A LiveCD is a CD or DVD that contains a bootable computer operating system. In this context, the file "livecd.sqfs" on the LiveCD would be the bootable disk image containing the Linux operating system files needed to run or install the system directly from the CD.
To open or use a .SQFS file, you need a system that supports the Squash FS file system. Typically, this would be a Linux system that has Squash FS support built-in. When you use such a system, you can mount the .SQFS file as if it were a physical disk and then access the files inside it or use it to boot and run or install the operating system.
In summary, the .SQFS file extension is crucial for distributing, installing, or running Linux systems efficiently, especially when using LiveCDs or similar media. It allows for a compact, secure, and efficient way to handle system files necessary for operating system functionality.
