What is an 3FS file?

The .3FS file extension is used by Puppy Linux, a lightweight Linux distribution designed for older hardware and ease of use. This file format is specifically associated with the save state files used by Puppy Linux.

More Information.

The .3FS file format was introduced as part of the Puppy Linux save file mechanism. Its primary purpose is to allow users to save their system state, including personal files, settings, and configurations, so that when they reboot or shut down the system, their environment can be restored to the exact state it was in before the shutdown. This is crucial for maintaining a consistent user experience across sessions.

Origin Of This File.

The .3FS file extension originates from the Puppy Linux operating system, which is known for its small footprint and portable nature. Puppy Linux employs the .3FS file format to store user data and settings.

File Structure Technical Specification.

  • File Structure: The .3FS file is essentially a file container or disk image that includes a file system structure. It uses the same file system as the host operating system but is encapsulated within a single file.
  • Technical Specification: The .3FS file format is a custom implementation used by Puppy Linux. It is designed to be compatible with the SquashFS file system, a compressed read-only file system commonly used in Linux distributions.

How to Convert the File?

Windows

  1. Extract Contents:
    • Using Linux Tools in Windows:
      • Install a Linux virtual machine or use Windows Subsystem for Linux (WSL).
      • Use Linux tools to mount or extract the .3FS file.
    • Using a Disk Image Tool:
      • Download and install a disk image tool like 7-Zip or PeaZip.
      • Open the .3FS file with the tool and extract its contents to a directory.
    • Using Puppy Linux:
      • Run Puppy Linux in a virtual machine or live environment.
      • Use the built-in utilities to mount or extract the .3FS file.
  2. Convert Extracted Files:
    • Once extracted, the contents of the .3FS file can be converted to other formats depending on their type (e.g., documents, images) using standard file conversion tools.

Linux

  1. Extract Contents:
    • Using squashfs-tools:
      • Install squashfs-tools if not already available: sudo apt-get install squashfs-tools
      • Use the command unsquashfs to extract the contents: unsquashfs yourfile.3fs
    • Using Puppy Linux:
      • Open Puppy Linux and use its built-in utilities to mount or manage the .3FS file.
  2. Convert Extracted Files:
    • Convert files as needed using relevant tools based on the file types extracted from the .3FS.

macOS

  1. Extract Contents:
    • Using Linux Tools in macOS:
      • Install a Linux virtual machine or use Homebrew to install squashfs-tools.
      • Use unsquashfs to extract the .3FS file.
    • Using Disk Image Tools:
      • Use a tool like The Unarchiver or Keka to extract contents if compatible.
    • Using Puppy Linux:
      • Run Puppy Linux in a virtual machine and manage the .3FS file within that environment.
  2. Convert Extracted Files:
    • After extracting, convert the files based on their types using standard macOS tools or conversion applications.

Android

  1. Extract Contents:
    • Using Termux:
      • Install Termux from the Google Play Store and use it to run Linux commands.
      • Install necessary packages and tools (e.g., squashfs-tools) and use them to extract the .3FS file.
    • Using a File Manager App:
      • Some advanced file manager apps may allow mounting or extracting disk images.
  2. Convert Extracted Files:
    • Convert files as needed using Android apps that handle specific file types.

iOS

  1. Extract Contents:
    • Using a Virtual Machine:
      • Set up a Linux virtual machine or use cloud-based Linux environments.
      • Extract the .3FS file using Linux tools available within the VM.
    • Using Apps or Jailbreak Tools:
      • If the device is jailbroken, you might use specialized apps or tools for file extraction.
  2. Convert Extracted Files:
    • Convert files based on their types using available iOS apps or through a computer.

Others

  1. Extract Contents:
    • Using Linux-Compatible Tools:
      • For devices that can run Linux tools or virtual environments, follow similar steps as above using squashfs-tools or equivalent tools.
  2. Convert Extracted Files:
    • After extraction, use available software or tools to convert files based on their types.

Advantages And Disadvantages.

  • Advantages:
    • Portability: The .3FS file allows users to carry their operating system and personal settings on a USB drive or other portable media.
    • Persistence: It provides a way to preserve user settings and files across sessions, which is beneficial for systems that run from live media.
    • Efficiency: The file system used within .3FS is compressed, which saves space and can speed up access times.
  • Disadvantages:
    • Compatibility: .3FS files are specifically designed for Puppy Linux and may not be easily used or recognized by other operating systems or Linux distributions.
    • Size Limitations: Depending on the size of the file system and the amount of data stored, .3FS files can become quite large, which may be a limitation for smaller storage devices.

How to Open 3FS?

Open In Windows

  • Puppy Linux Tools: You can use tools like 7-Zip or similar utilities to extract the contents of a .3FS file, but handling the extracted files may require additional steps or software.
  • Virtual Machines: Running Puppy Linux in a virtual machine on Windows allows you to open and use .3FS files natively within the operating system.

Open In Linux

  • Puppy Linux: .3FS files are natively supported by Puppy Linux. You can use the built-in utilities to manage these files directly.
  • Other Linux Distributions: You can use tools like mnt or squashfs-tools to mount or extract the contents of a .3FS file.

Open In MAC

  • Virtual Machines: Running Puppy Linux in a virtual machine on macOS allows you to open and use .3FS files.
  • File Extraction Tools: Extracting the contents might require additional software or command-line tools to handle the file system within the .3FS file.

Open In Android

  • Emulation: Running a Linux environment or virtual machine on Android can provide access to .3FS files.
  • File Extraction: Direct handling of .3FS files on Android is generally not supported; specialized apps or tools may be required.

Open In IOS

  • Emulation or Virtual Machines: Similar to Android, accessing .3FS files on iOS would require running a compatible environment or using specialized tools.
  • File Handling: iOS does not natively support .3FS files, so third-party solutions or workarounds are necessary.

Open in Others

Portable Devices: Accessing .3FS files on other portable or embedded devices would depend on the device’s capability to handle Linux-based file systems and formats.
